Encapsulation of Polyethylene for Strontium Aluminate Phosphors to Enhance its Water Resistance


Article Preview

Phosphors of SrAl2O4:Eu2+, Dy3+ were encapsulated with polyethylene plastic film by a physical technology. Water resistance measurements, Fourier transform infrared spectroscopy (FT-IR), thermogravimetric (TG) analysis, and photoluminescence (PL) spectrophotometry were used to characterize the phosphors Results showed that the encapsulated layer was a thin film with an encapsulation amount of 4.0 wt%, and encapsulation can effectively improve the water-resistance for the phosphor without any destroy of crystal structure of phosphors.
