Anti-Stokes Photoluminescence from CsPbBr3 Nanostructures Embedded in a Cs${}_4$PbBr${}_6$ Crystal

Yuto Kajino, Shuji Otake, Takumi Yamada +6

Lead halide perovskites possess high photoluminescence (PL) efficiency and strong electron-phonon interactions, and therefore the optical cooling using up-conversion PL has been ex…
