Abstract
We investigated the effect of processing conditions in low-temperature plasma on luminescent characteristics of AIIBVI phosphors. As a result of treatment, the luminescence spectra of all tested phosphors shifted to longer wavelengths, which was caused by change of quantities of luminescent centers due to the redistribution (diffusion) of the activator in the crystal lattice. In the case of ZnS:Cu,Cl and ZnS:Cu,Al phosphors brightness increased as a result of treatment. Therefore when phosphors were plasma coated with protective MgO encapsulation both brightness and stability were improved at the same time.
