Paper Abstract

This work presents new data concerning CsPbCl3 crystal luminescence. Six maxima are evidenced in the low temperature (77 K) spectrum. The paper emphasize the particular behavior of one of them, located at 23880 cm-1: it presents an almost quadratic dependence on the excitation intensity, a gradual Stokes shift and a decrease of its FWHM. This band is fastest quenched by temperature rising and it also exponentially grows with respect to the length of the excited area. These peculiarities led us to the conclusion that this band must be assigned to a stimulated emission due to an exciton-exciton inelastic collision process.
