were successfully synthesized by hydrothermal process with a subsequent annealing treatment. The crystallization and microstructures of the samples were characterized by powder X-ray diffraction (XRD) and scanning electron micrograph (SEM). The luminescent properties of the prepared samples were investigated by the excitation and emission spectra. Under 389 nm excitation
the emissions centered at 487 nm and 576 nm were attributed to the transitions of

which is closest to the nature white light. Thus it can be considered to be a potential candidate for white-LEDs.
