Abstract

High resistivity CdTe:In samples were studied by means of continuous and picosecond time-resolved photoluminescence (PL). The detected PL signal is affected by non-radiative trapping, while radiative recombination has an excitonic character. Two recombination lifetimes describe the measured time-resolved PL spectra: the first (30-60 ps) takes into account fast non-radiative recombination; the second lifetime is in the range 200-300 ps and can be related to exciton decay .
