The luminescence properties of Yb3+ and Nd3+-activated strontium-silicon-oxynitrides have been studied by hydrothermal synthesis process. The X-ray diffraction (XRD) measurement, absorption spectrum, and photoluminescence spectrum of the powder phosphors were presented. It absorbs light efficiently in the blue region (450 nm~500 nm), that shows a single intense broadband emission at 570 nm. Then SrSi...
