Abstract
Manganese-doped zinc sulfide (ZnS:Mn) thin films were grown by evaporation of ZnS:Mn powder using a CO2 laser. Microprobe analysis and X-ray diffraction identify the films as stoichiometric cubic and hexagonal ZnS:Mn. Scanning electron microscopy shows that the films are smooth but crazed, which is due to the mismatch in thermal expansion coefficient between ZnS:Mn and the fused silica substrate. Photoluminescence measurements of the powder shows the broad luminescence spectrum centered at around 590 nm and a fluorescent lifetime of 330 μs. The emission peak of the thin film is shifted to 596 nm and has a fluorescent lifetime of 240 μs.
