11 February 2010 Blue-emitting Sr3Ga2O5Cl2:Eu2+ phosphor for white-light-emitting diode
Author Affiliations +
A novel blue-emitting phosphor, Sr3Ga2O5Cl2:Eu2+, was synthesized by a two-step solid-state reaction. It has the monoclinic structure with six different cation sites. It shows an efficient broad absorption band around the 400 nm of the commercial near ultraviolet light-emitting diodes (LEDs), and an intense broad blue emission. Thus, it can be a promising blue phosphor for white LED for solid state lighting.
