More Information
Summary:The invention provides a reversible photochromic material which has a general formula of Y3Al5-xGaxO12:yNi<2+>, wherein x is more than or equal to 0 but less than or equal to 5, and y is more than 0 but less than or equal to 0.02. Reversible photochromism between no color and brownish red is realized through transition metal ion Ni<2+>-doped aluminum gallium acid salt, and meanwhile, the reversible photochromic material also has a near infrared long-afterglow luminescence property. 本发明提供了种可逆光致变色材料，通式为：YAlGaO:yNi，其中，0≤x≤5，0＜y≤0.02。本发明通过过渡金属离子Ni掺杂铝镓酸盐实现无色与棕红色之间的可逆光致变色，同时这种光致变色材料还具有近红外长余辉发光性能。
