Size effect of silver nano particles on the photophysical properties of 2,3-bis(chloromethyl)anthracene-1,4,9,10-tetraone (BCMAT) have been investigated using optical absorption and fluorescence emission techniques. Silver NPs of different sizes have been prepared by two different methods. Quenching of fluorescence of BCMAT has been found to increase with decrease in the size of the silver NPs. Stern–Volmer quenching constants have also been calculated.
利用光学吸收和荧光发射技术研究了纳米银粒子的尺寸对 2,3-双(氯甲基)蒽-1,4,9,10-四酮(BCMAT)光物理性质的影响。通过两种不同的方法制备了不同大小的银 NPs。研究发现,BCMAT 的荧光淬灭随银 NPs 尺寸的减小而增加。此外,还计算了斯特恩-沃尔默淬灭常数。
