A new kind of glass-ceramic phosphor,which contains crystalline phases with green emissions,is explored.The glassceramic is prepared through semi-melt-quenching procedure with a nominal composition of(Ca0.99Eu0.01)3Si2O7.The greenemitting crystals are precipitated and identified to be β-Ca2SiO4:Eu2+ which is responsible for 510 nm-peaked muchbroader band emissions holding at 1550 oC for half an hour.In terms of the available light scattering theory,the appearance of opaque is discussed by closely associating with size and morphology of luminous β-Ca2SiO4 crystalline phase in glass.
