Abstract

Thin film electroluminescent (TFEL) display structures have been produced by sol-gel technology, with the active layer comprising doped zinc sulphide films produced by the sulphidation of sol-gel deposited zinc oxide thin films. The luminescent properties of display structures using manganese-doped zinc sulphide, which has a strong orange emission due to the Mn²⁺⁴ T₁(4G) ⁶A₁(⁶S) transitions have been investigated using photoluminescence (PL), cathodoluminescence (CL), and electroluminescence (EL) and the correlation between the luminescence produced by the various methods has been studied. A comparison of the spectra using PL, CL and EL has shown how these excitation methods can be used to quantify the electroluminescence produced by the zinc sulphide. The effects of the interaction between the insulating layer and the emission layer have also been studied.
