 Abstract
The green emitting phosphor has been studied as a luminous device for CRT (Cathode Ray Tube) or FED (Field Emission Display) and EL (Electroluminescence). This phosphor, also, is under noticed for LED (Lighting Emitting Diode) phosphor, which makes use of excitation characteristics of long wavelength region. The phosphor was prepared generally conventional synthesis method using flux. However, this method needs high heat-treated temperature, long reaction time, complex process and harmful or gas. In this works, therefore, we have synthesized using SrS, , and EuS as starting materials, and the mixture gas of 5% H2/95% N2 was used to avoid the or . We investigated the luminescence characteristic of phosphor prepared in various synthesis conditions, performed post-treatment and sieving process for application to LED.
