摘要
研究了水杨酸不同溶剂下三维荧光性质的影响,对水杨酸在不同溶剂中的激发光谱和发射光谱的研究表明:在不同溶剂中水杨酸的荧光性质发生改变,激发峰和发射峰分别发生一定位置的偏移,影响一般溶剂效应的主要因素是溶剂的介电常数,由于介电常数的不同,水杨酸在不同溶剂中发射峰位置发生红移的幅度有所差别,且呈现一定规律。
Salicylic acid acetone on the pyridine methanol to ethanol acetonitrile ethyl acetate fluores- cence properties of salicylic acid,salicylic acid in different solvents in the excitation spectrum and emission spectra of the study show that:in different solvents Salicylic acid fluorescence in the nature of change, stimulated emission peak and peak occurred a certain location of the migration.Impact on the general sol- vent effect is the main factor solvent dielectric constant,due to the different dielectric co...
