PHOSPHOR PARTICLES AND METHOD FOR PREPARATION THEREOF, DISPLAY PANEL AND METHOD FOR MANUFACTURE THEREOF, AND PLANE DISPLAY DEVICE AND METHOD FOR MANUFACTURE THEREOF

摘要

A method for preparing phosphor particles, which comprises reacting water glass with an acetate or a nitrate in a liquid mixture of water glass, phosphor particles, and an acetate or a nitrate, to thereby form a glass-like thin film comprising silicon oxide (SiOx) as a primary component on the surface of the phosphor particles.
