这封信涉及 2,5-二苯基恶唑 (PPO) 在脉冲 532 nm 固态激光器照射下的双光子激发,平均功率为 30 mW,重复率为 20 MHz。 PPO 在接受单光子和双光子激发时获得了非常令人满意的发射光谱位置和形状,这表明两种激发模式涉及相同的激发态。此外,还记录了发射强度函数中激光功率的完美二次相关性。我们测试了小型固态绿光激光器在双光子诱导时间分辨荧光中的应用,结果表明,双光子激发的 PPO 发射各向异性明显高于单光子激发。
This Letter concerns two-photon excitation of 2,5-Diphenyloxazole (PPO) upon illumination from a pulsed 532 nm solid state laser, with an average power of 30 mW, and a repetition rate of 20 MHz. A very agreeable emission spectrum position and shape has been achieved for PPO receiving one- and two-photon excitation, which suggests that the same excited state is involved for both excitation modes. Also, a perfect quadratic dependence of laser power in the emission intensity function has been recorded. We tested the application of a small solid state green laser to two-photon induced time-resolved fluorescence, revealing the emission anisotropy of PPO to be considerably higher for two-photon than for one-photon excitation.
