phosphor was prepared by high temperature solid state method. The phosphor has a strong absorption in the ultraviolet band in the range of 300 to 400 nm. With the excitation of 375 nm
this phosphor exhibits two broad emission bands
peaked at 550 and 615 nm. And under the excitation of 393 nm
this phosphor exhibits a strong broad emission band
peaked at 615 nm due to the
