Study on UV new laser dye IBOP

本文介绍一种新合成的化合物IBOP.经在多种染料激光器上测试表明,其激光转换效率高,光化学稳定性好,能溶于多种溶剂.性能优于DPS等相同波段的常用激光染料.IBOP在各种溶剂中的激光调谐范围为388～428nm,激光峰值波长在400nm左右.本文给出了IBOP的荧光光谱、吸收光谱、激光特性、溶剂效应和浓度效应等数据,并作了讨论.

A new compound 1, 4-Bis (5', 7'-Bis-ipr-1', 3'-benzoxazolyl-2') benzene to be used as ultraviolet laser dye and named as IBOP, is introduced. Compared with the oorrespounding laser dye DPS, the IBOP has shown its better lasing properties including high conversion efficiency, photochemical stability and good solubility. In the experiments, the new dye was pumped by XeCl exoimer laser (308 nm), N2 laser (337 nm) and YAG laser with 3 rd harmonic frequency (355 nm). It is found that the compound IBOP is working in the spectral region of 388 nm to 428 nm and the laser peak wavelengths are around 400 nm in different solvents with nitrogen laser excitation. The experimental data of fluorescence spectra,UV absorption spectra, fluorescence lifetime and quantum yields of IBOP, as well as the effects of concentration and solvents, are also reported. A brief discussion is given.
