荧光粉涂屏后亮度降低与涂屏时感光胶中铬离子的残余有关。 例如,145克Y_2O_2S∶Eu、21克聚乙稀醇水溶液、0.95克重铬酸铵加100克纯水做
The decrease of brightness after the phosphor screen is related to the residual of chromium ions in the photoresist when the screen is coated. For example, 145 grams of Y 2 O 2 S: Eu, 21 grams of polyethylene glycol aqueous solution, 0.95 grams of ammonium bicarbonate plus 100 grams of pure water to do
