electroluminescent phosphor
1.MAINTENANCE OF ZnS-Cu,Eu,Br ELECTROLUMINESCENT PHOSPHOR UNDER AC FIELD EXCITATION
2.In order to prolong the lifetime of the phosphor, Na2SiO3 liquid phase hydrolyzation and atmospheric chemical vapor deposition of TEOS and O2 is adopted to form coating of silicon dioxide film on the surface of the electroluminescent phosphor ZnS: Cu in this paper for the first time.
3.Electroluminescent (EL) displays produce light when electrons hit a phosphor layer sandwiched between two insulating layers.
