Evaluation of CsPbBr3 nanocrystals for laser cooling (Conference Presentation)
Author(s): Masaru K. Kuno

Paper Abstract

CsPbBr3 nanocrystals possess optical properties amenable to achieving verifiable condensed phase laser cooling. This includes near unity emission quantum yields, a high tolerance to defects, and efficient up-conversion. We have previously demonstrated emission QYs that approach unity as well as up-conversion efficiencies that range from ~30% to 75%, depending on sub gap excitation energy. Emission up-conversion is also seen at the individual nanocrystal level. In this presentation, I will discuss our latest results on evaluating CsPbBr3 nanocrystals for the purpose of demonstrating condensed phase laser cooling.
