A facile route for highly efficient color-tunable Cu-Ga-Se/ZnSe quantum dots

• Color-tunable Cu-Ga-Se/ZnSe quantum dots (QDs) were firstly obtained via a facile heating-up method. • The synthesis process is highly efficient and environmentally-friendly. • The tunable emission (485–630 nm) can be acquired by introducing sulfur ion and varying the Cu/Ga molar ratio. • The QDs...
