Abstract

Frequency-resolved spectroscopy (FRS) has been used to determine the lifetime distribution of the mid-gap photoluminescence (PL) band in phosphorus selenide glasses a-P_xSe_1-x, where x = 0.67, 0.75, 0.84, and in c-P₄Se₃. Exceptionally narrow distributions are found, peaking near a frequency of 1kHz in all cases, with widths close to the experimental resolution. The lifetime of the PL band is found to be almost independent of the excitation energy and intensity, up to a certain limit. This result is evidence for geminate recombination in the phosphorus selenides. The similarity between glasses and crystal indicates a common recombination centre, which is believed to be a consequence of the similar microstructure in the two cases.
