Abstract
The effects of Li codoping in ZnS:TmF3 thin‐film electroluminescent devices are reported. ZnS:Tm, Li thin films are prepared at several Li concentrations and substrate temperatures. The electroluminescent characteristics of ZnS:Tm,Li devices depend on Li concentrations, substrate temperatures, the annealing, and drive voltages.Keywords
