Abstract
⺠Photoluminescence of the Cr3+ centers was studied under Vis-UV-VUV excitation. ⺠The excitons bound to impurity centers in nanoscale α-Al2O3 crystals are observed. ⺠Size dependence of the bound exciton manifestation has been found. ⺠Effect of electron excitation multiplication is observed at an energy more than 2Eg.
