Zhejiang Daxue xuebao. Lixue ban, 2004 用溶胶-凝胶法合成了发蓝绿光的4SrO·7Al2O3:Eu2+高显色荧光粉.从XRD、DTA以及红外谱图得出当干凝胶经1200℃灼烧可以完全形成4 SrO·7Al2O3晶相,这比用高温固相合成法低了200℃.通过激发光谱和发射光谱分析其发光特性,随着灼烧温度的升高,其发光强度增大.

Zhejiang Daxue xuebao. Lixue ban, 2014 钯(Pd)是一种性质非常特殊的稀有过渡金属，在化学以及材料科学中具有重要地位.钯催化反应的产物中常有一定浓度的残余钯污染，需要进一步纯化和检测.因此发展用于检测Pd的技术手段很有必要.零价钯可以通过对烯丙基氧化插入而切断烯丙基醚类化合物的C—O键.基于这个反应，设计合成了荧光分子二氟硼姜黄素烯丙基醚化合物，并测试了其紫外光谱和荧光光谱，研究了其对钯化合物的选择性识别作用.结果表明，该荧光分子对二价钯并无响应，只有零价钯Pd2(dba)3使该分子荧光发生猝灭.该荧光分子对于零价钯表现出很好的选择性和响应性，

四川大学学报. 自然科学版, 2009 研究了曲酸对胰蛋白酶活性的影响,以及曲酸处理的胰蛋白酶的紫外光谱、荧光淬灭光谱、同步荧光光谱和三维荧光光谱.结果显示曲酸对胰蛋白酶具有激活作用;二者相互作用后,曲酸可以使胰蛋白酶的紫外吸收强度增强,但却使得蛋白内源荧光强度下降.Stern-Volmer作图显示了曲酸对胰蛋白酶的荧光淬灭为静态淬灭作用,求出二者的结合常数K为5.30×10～7L/mol,结合位点n为1.50;用同步荧光光谱和三维荧光光谱探讨了曲酸对胰蛋白酶构象的影响.
