Abstract
Blue emitting Sr2Ga2S5:Ce phosphor thin film has been first grown by multisource deposition. The evaporating source materials are Sr metal and Ga2S3 compound, and the dopant is CeCl3. This polycrystalline thin film shows the single orientation of (004). The SrS thin film is a buffer layer underneath the Sr2Ga2S5 thin film and is necessary for growth. The photoluminescence spectrum by excitation of the UV light at 290 nm is a broad band with two peaks at 443 and 484 nm, that is originated from D–42F5/2,7/2 transitions of Ce3+ ion. The emission is a saturated blue color and the Commission International de l’Eclairage chromaticity coordinates are x=0.15 and y=0.12.
