description

Spectral characteristics of native defects from the crystalline lattice of c-BN were studied. It is found that the photoluminescence (PL) spectrum under exposure to ultraviolet-blue light has a complex structure containing a predominant wide 2.5 eV luminescence band at room temperature. The photostimulated luminescence (PSL) consists of a band, which is coincident with the 2.5 eV PL. The results obtained allow to conclude that the same defects are responsible for both the PL and PSL formation.
