Abstract— The voltage ( V ) dependences of the luminance and transferred charge of ZnS:Er,F TFELS prepared by varying the annealing temperature ( Tann ) are given at different frequencies ( f ). The change in the relative intensity of the green band (523 nm) and the near‐infrared bands (983 and 1530 nm) in the emission spectrum when V, f , and Tann are varied is also considered. The influence of the annealing temperature on the energy spectrum of defects in ZnS:Er,F film was studied by photodepolarization spectroscopy. The revealed effect of the above excitation and preparation conditions on the radiative characteristics is discussed.
