Study of ultraviolet light-induced aging of ZnS phosphor powder by two-beam photoacoustic spectroscopy

Journal Article


Abstract


  • A two-beam photoacoustic technique is employed to monitor ultraviolet light-induced darkening of ZnS (Mn, Cu) powder used for large-area electroluminescent panels. The darkening process occurs for ultraviolet irradiation at wavelengths less than 345 nm. Photoacoustic measurements are made of the light-induced change in the absorption spectrum and the influence of doping and contamination by atmospheric water on darkening rates.
