Abstract

AbstractThe photoluminescent intensities of nanocrystal ZnS:Tb and ZnS:Eu synthesized by the new method were 2.5 and 2.8 times stronger than those of bulk (conventional). Furthermore, taking charge compensation into account, the luminescent efficiencies of nanocrystal ZnS:Tb and ZnS:Eu could be improved. Cathodoluminescence of nanocrystal ZnS:Tb and ZnS:Eu could be successfully observed for the first time. These nanocrystal phosphors are considered for applications in FED, EL, PDP and CRT.
