Abstract:

以吲哚啉螺苯并吡喃(indolinespiropyrans,SP)和SrAl2O4(Eu2+,Dy3+)(SAO-ED)发光粉为原料,采用界面配位键合方法在SAO-ED发光粉的表面包覆SP制备了SP/SAO-ED复合发光粉。通过X射线衍射、X射线光电子能谱、Fourier红外光谱表征了SP/SAO-ED复合发光粉的晶体结构和表面涂层组成;用紫外光谱、激发和发射光谱分析了该复合发光粉的光致发光性能和光致变色性能。结果表明SP/SAO-ED复合发光粉由SAO-ED表面的金属离子与SP杂环上的N原子配位结合而成;该复合发光粉不但具有SAO-ED发光粉的晶体结构和光致发光性能,还具有SP的光致变色性能。
