摘要
合成了 4个蓝 -绿波段的激光染料 ,测定了它们的光谱数据和激光性能 ,结果表明含三氟甲基的 2个染料具有较宽的调谐范围 :470~ 540nm和 456~ 51 6nm ;较高的激光效率 :41 4%和2 6 6%。同时 ,分别采用Nicol理论和Lippert理论对其中 2个香豆素型激光染料的吸收光谱和发射光谱的溶剂效应进行了研究 ,揭示了染料Stokes红移的内在本质。
Four lasing dyes in blue-green scale were synthesized. The spectra and lasing properties of these dyes were determined.Two of them which containing trifluoromethyl group had wide laser tuning ranges (470-540 nm and 456-516 nm) and showed high lasing efficiencies (41 4% and 26 6%).Meanwhile,by using Nicol theory and Lippert theory,the solvent effects on the absorption and fluorescent spectra of two coumarin dyes in organic solvents were studied.The inherent nature about Stokes shift of dyes was revealed.
