A study of the (Y,Gd)BO3:Eu3+ phosphor coated with nano-sized oxide particles for the plasma display panel

摘要

The surface of (Y,Gd)BO3:Eu3+ phosphor, red-emitting source in the plasma display panel (PDP), was coated with nano-sized oxide particles(SiO2, Al2O3 and ZnO) in a simple surface treatment way, a kind of the modified sol-gel method. It was found that the surface coating of red phosphors with nano-particles leads to an increase in the luminance intensity of the test panel, similar to the PDP and the gas discharge lamps in the device structure.
