摘要
利用超声法,以7-羟基香豆素和γ-Al2O3纳米粉为原料,成功地制备出了γ-Al2O3/7-羟基香豆素纳米复合发光材料。测试结果表明:由于γ-Al2O3纳米粉和7-羟基香豆素之间的相互作用,所制得的复合材料的荧光强度明显高于原料本身的强度。此外,还研究了7-羟基香豆素溶液的浓度和超声处理的时间对复合材料荧光性能的影响。
Using γ-Al2O3 nanoparticles and 7-hydroxycoumarin as the starting materials,γ-Al2O3/7-hydroxycoumarin fluorescent nanocomposites were successfully synthesized by an ultrasonic method.The samples were characterized by fourier transform infrared spectroscopy（FTIR） and photoluminescence spectroscopy.The results showed that chemical reaction occurred between γ-Al2O3 nanoparticles and 7-hydroxycoumarin molecules.The PL intensity of γ-Al2O3/7-hydroxycoumarin nanocomposites is much higher than that of both γ-Al2O3 nanoparticles and 7-hydroxycoumarin particles.In addition,the effects of 7-hydroxycoumarin concentration and ultrasonic radiation time on photoluminescence property of the nanocomposites were also investigated.
