(Color online) (a) Temperature-dependent PL spectra of ZnSe0.950Te0.050 and (b) corresponding PL peak energy versus temperature. Dashed curve in (a) is PLE spectrum of ZnSe0.950Te0.050, detected at the PL peak and 10 K. The black arrow indicates the band edge. Inset in (b) schematically depicts carrier decay paths; only three trap states are considered for simplicity.
(Color online) Temperature-dependent (a) TRPL spectra, (b) PL lifetime τ (open circles) and radiative lifetime τr (solid circles), (c) stretching exponent β, and (d) integrated PL intensity IPL of ZnSe0.950Te0.050. Inset in (a) shows TRPL spectra on a double logarithmic scale. The solid line in (b) is the fitting result of τr using Eq. (1).
(Color online) TRPL images of ZnSe0.950Te0.050 at (a) 10 K and (b) 160 K.
