  Photo- and roentgenoluminescence of ZnSe

  摘要：

  The photoluminescence (PL), roentgenoluminescence (RL), and optical absorption of ZnSe were measured near the fundamental edge in the temperature range from 80 to 400 K. Because of the much smaller absorption coefficient for x-rays as compared to visible light, the contribution to RL from emitting centers located deeper in the sample is higher. The quality of ZnSe can be assessed by correlating its near-edge PL and RL spectra. The temperature dependences of the peak positions of the blue PL and RL bands indicate that these emissions are due to the same center. The blue RL band is redshifted by 18 meV in comparison with Pt,, and its intensity is lower than that of the longer wavelength bands. The different positions of the PL and RL bands are interpreted in terms of thermal spike formation under x-ray excitation and reabsorption of the emitted light.
