Abstract
The capture times of holes to the ground level of the neutral mercury vacancy in a solid solution of Hg1-xCdxTe during the emission of an optical phonon are calculated. The calculation showed that this process can compete with the capture of holes into small excited states of vacancy centers with the emission of acoustic phonons. Such competition can lead to quenching of lines in the spectrum of vacancy photoluminescence of Hg1-xCdxTe layers with increasing temperature. Keywords: mercury vacancy, optical phonon, non - radiative transition.
