Nd3+-doped TiO2 nanocrystals: Structural changes, excited-state dynamics, and luminescence defects
The structural and optical properties of the TiO2 nanocrystals (NCs) samples pure and doped with Nd3+ ions were studied as a function of temperature. These properties were studied by using the Raman spectroscopy, steady-state and time-resolved photoluminescence. A structural transformation is observ...

520 | |a The structural and optical properties of the TiO2 nanocrystals (NCs) samples pure and doped with Nd3+ ions were studied as a function of temperature. These properties were studied by using the Raman spectroscopy, steady-state and time-resolved photoluminescence. A structural transformation is observed by a systematic study as a function of the temperature from room temperature. The results show that the introduction of Nd3+ ions and the increase of temperature induces a phase transformation from anatase to brookite. As a result, the intrinsic defects states of TiO2 NCs decrease and consequently the PL intensity of the 4F3/2 level of Nd3+ ions increases. The photoluminescence decay kinetics also shows that Nd3+ ions are located in two different environments of TiO2 NCs: the brookite and anatase phase. | ||

The results show that the introduction of Nd3+ ions and the increase of temperature induces a phase transformation from anatase to brookite. As a result, the intrinsic defects states of TiO2 NCs decrease and consequently the PL intensity of the 4F3/2 level of Nd3+ ions increases. The photoluminescence decay kinetics also shows that Nd3+ ions are located in two different environments of TiO2 NCs: the brookite and anatase phase.</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Phase transformation</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Nanocrystals</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Nd-luminescence</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Brookite phase</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">TiO2 nanocrystals-Raman</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">TiO2 nanocrystals-temperature</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Anatase phase</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Titanium dioxide</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Anatase to brookite phase</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Filho, José C.S.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Messias, Djalmir N.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Pilla, Viviane</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Dantas, Noelio O.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Silva, Anielle C.A.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Andrade, Acácio A.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="n">Elsevier</subfield><subfield code="a">Liu, Chang ELSEVIER</subfield><subfield code="t">New ablation evolution behaviors in micro-hole drilling of 2.5D C</subfield><subfield code="d">2021</subfield><subfield code="g">New York, NY [u.a.]</subfield><subfield code="w">(DE-627)ELV00662605X</subfield></datafield><datafield tag="773" ind1="1" ind2="8"><subfield code="g">volume:240</subfield><subfield code="g">year:2021</subfield><subfield code="g">pages:0</subfield></datafield><datafield tag="856" ind1="4" ind2="0"><subfield code="u">https://doi.org/10.1016/j.jlumin.2021.118461</subfield><subfield code="3">Volltext</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_USEFLAG_U</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ELV</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SYSFLAG_U</subfield></datafield><datafield tag="936" ind1="b" ind2="k"><subfield code="a">51.60</subfield><subfield code="j">Keramische Werkstoffe</subfield><subfield code="j">Hartstoffe</subfield><subfield code="x">Werkstoffkunde</subfield><subfield code="q">VZ</subfield></datafield><datafield tag="936" ind1="b" ind2="k"><subfield code="a">58.45</subfield><subfield code="j">Gesteinshüttenkunde</subfield><subfield code="q">VZ</subfield></datafield><datafield tag="951" ind1=" " ind2=" "><subfield code="a">AR</subfield></datafield><datafield tag="952" ind1=" " ind2=" "><subfield code="d">240</subfield><subfield code="j">2021</subfield><subfield code="h">0</subfield></datafield></record></collection>

Nd3+-doped TiO2 nanocrystals: Structural changes, excited-state dynamics, and luminescence defects |
abstract |
The structural and optical properties of the TiO2 nanocrystals (NCs) samples pure and doped with Nd3+ ions were studied as a function of temperature. These properties were studied by using the Raman spectroscopy, steady-state and time-resolved photoluminescence. A structural transformation is observed by a systematic study as a function of the temperature from room temperature. The results show that the introduction of Nd3+ ions and the increase of temperature induces a phase transformation from anatase to brookite. As a result, the intrinsic defects states of TiO2 NCs decrease and consequently the PL intensity of the 4F3/2 level of Nd3+ ions increases. The photoluminescence decay kinetics also shows that Nd3+ ions are located in two different environments of TiO2 NCs: the brookite and anatase phase. |
