Abstract

Temperature dependence of the excitonic and biexcitonic emissions in cubic ZnS single crystals has been studied by photoluminescence technique. We observed the very well-resolved excitonic and biexcitonic emissions from cubic ZnS single crystals with very low excitation density, in the tens-of-milliwatts-per-square-centimetre range. The kinetic energy contribution to the shift with temperature of the biexcitonic emission was determined showing a characteristic difference with the normal shift caused by the temperature-narrowed band gap.
