- Abstract
The electroluminescence (EL) spectra of ZnS:Mn thin-film emitters measured in various regions of the luminance wave exhibit, besides the bands characteristic of the intracenter emission from Mn[sup 2+] ions, additional EL bands peaked at ∼530 and ∼655 nm, which are probably related to the trapping of free electrons on deep centers formed by the sulfur vacancies V[sup 2+, sub s] and V[sup +, sub S]. These traps may lead to the formation of a negative bulk charge in a near-cathode region, inducing a decrease in the growth rate (or even a drop) of current through the phosphor, as well as a decay of instantaneous luminance.
