Green zincate fluorescent powder and preparation method thereof

The invention relates to the technical field of luminescent materials. A green zincate fluorescent powder has a chemical formula as follows M3Zn2-XO8: xMn2+, M is any one of Si, Ge, Ti, Zr, Sn and Te, and x is 0.001-0.1. The green zincate fluorescent powder has the advantage that more expensive rare earth elements are not contained, the powder has a wide excitation bandwidth having ultraviolet, violet light and blue light zones, emission peak overlapping with an ultraviolet chip is good, and the powder can be effectively excited. 本发明涉及发光材料技术领域。种锌酸盐绿色荧光粉，具有如下化学表示式：MZnO：xMn，M为Si、Ge、Ti、Zr、Sn、Te中任意种，x为0.001～0.1。该锌酸盐绿色荧光粉的优点是不含价格较为昂贵的稀土元素，具有宽的激发带宽，覆盖紫外、紫光和蓝光区域，与紫外芯片的发射峰重叠好，能够有效被激发。
