Abstract

ZnS:Mn has been studied as a yellow phosphor for the application to fluorescent displays operated at low voltage. It was found that luminescence of $Mn^{2+}$ ion from hexagonal phase of ZnS was suitable for the display applications. The main emission peak was shifted to shorter wavelength when Cu ions were doped. The luminescence color of ZnS:Mn phosphor could be changed with decrease of its brightness.
