Li+-Induced Enhancement of Excitonic Luminescence in γ-CuBr Single Crystals Grown by the Vertical Bridgman Method

Abstract The intrinsic defects in pure γ-CuBr crystal lead to obvious nonradiative recombination, thereby significantly suppressing its ultrafast free-exciton emission. In this study, we successfully grew undoped and Li+-doped CuBr:x%Li (x = 0, 1, 3, 5) single crystals using the...
