Treatment of ZnS:Mn Phosphors by Partial Sublimation of SnO2:Sb Xerogel

SnO2:Sb xerogel was prepared using the sol-gel technique with SnCl2 center dot 2H(2)O and SbCl, as the starting materials. Partial sublimation of SnO2:Sb xerogel during oxidation was utilized to treat the as-prepared ZnS:Mn phosphor. The mass ratio of SnO2:Sb xerogel to ZnS:Mn phosphors changed from
