Abstract

The effects of oxygen codoping on ZnS1-xTex:CeF3 thin-film electro-luminescent devices are reported. ZnS1-x Tex:CeF3 (x = 0 and 1.25 x 10(-3)) films are prepared at substrate temperatures of 200-degrees-C and 300-degrees-C in vacuum and in oxygen remarkably. X-ray diffraction studies showed that the film orientation of the (111) plane and film uniformity are markedly improved when the films are prepared at 300-degrees-C in oxygen atmosphere. The emissive peak position and intensity ofZnS1-xTex:CeF3 devices change with substrate temperature and annealing, depending on the background atmosphere during film deposition. Oxygen codoping at a higher substrate temperature leads to an enhancement of luminance.
