ABSTRACT
Optical transmission in the range of fundamental absorption edge of Hg1-x-yCdxMnySe (x=0.09-0.11, y=0.02-0.03) single crystals is investigated at temperature varying from 5 K to 300 K. It is ascribed to band-to-band transitions with account of band-tail absorption. Infrared photoluminescence is detected for the first time in the mercury selenides compounds, flaring up at temperature increase. Energy gap and principal optical characteristics temperature dependences are determined for the compounds under investigation.
