【摘要】 观察到碘分子在光谱线514.5nm感应作用下的荧光谱,同时得到了在514.5nm附近碘分子的激发光谱。这两种谱的测量和研究表明,两能极模型对碘分子是一个很好的近似,普通光感应的碘分子荧光谱明显不同于激光感应的碘分子荧光谱。 在上面测量和研究的基础上,建立了新的物理模型以应用到激光感应荧光测量技术中。在488.0～544.0nm间,观察到了碘分子的激光感应荧光。更多还原

【Abstract】 We have observed the fluorescene spectrum of molecular iodine,induced by line at 514. 5nm,and have also got the excitation spectrum of molecular iodine near 514. 5nm. Measurement and study of both of such spectra show that a two-level model is a good approximation for molecular iodine. Obviously,the fluorescence spectrum of molecular iodine induced by ordinary light source is different from that induced by laser.Based on the measurement and study above,we’ve established a new physical model for application to the laser-induced fluorescene technique.From 488. 0nm to 544. 0nm,we have observed the laser fluorescence of molecular iodine.更多还原
