溶胶-凝胶法合成SrAl2O4∶Eu2+,Dy3+发光材料及其影响因素
Synthesis of SrAl2O4∶Eu2+,Dy3+Phosphors by Sol-gel Method and Its Influencing Factors
摘要
Abstract
SrAl2O4∶Eu2+,Dy3+are commercial materials with green persistent luminescence,which have shown actual applications in many fields.The SrAl2O4∶Eu2+,Dy3+ phosphors were synthesized by the the sol-gel method.We guided the students with the control variate method to analyze the influences of the key factors such as aluminum/strontium adding ratio,aluminum/urea adding ratio and calcining ambience on the luminescence and redox properties of SrAl2O4∶Eu2+,Dy3+ phosphors.The optimum preparation conditions of SrAl2O4∶Eu2+,Dy3+ materials played important roles on the chemical production.This work is helpful to train students'scientific research and experimental operation abilities,and provides an important referring example for the optimization of samples quality and luminescence properties of SrAl2O4∶Eu2+,Dy3+ materials.关键词
