Quantum Dot Phosphors Containing None of Hazardous Element; ZnTe-Based Alloy Quantum Dots

摘要

Green and narrow-band photoluminescence at 535 nm with 30 nm of FWHM was recently achieved by Zn(Te,Se) alloy QDs, and the potential of Zn(Te, S) alloy QDs as a red phosphor was theoretically demonstrated. In this paper, the recent progress in cadmium-free QD is reviewed focusing on ZnTe-based alloy QDs.
