一般描述
2,5-二苯基噁唑 (PPO) 是一种噁唑，可作为闪烁试剂和激光染料。它的荧光波长为375nm。凭借高量子产率和大斯托克斯位移，它可作为液体样品的波长位移剂。
应用
PPO可作为提高塑料闪烁体光电反馈的掺杂剂，后者可作为核材料的辐射探测器。它可包被多肽底物形成放射性标记，用于确定赖氨酸甲基转移酶的底物特异性。它还可用于合成有机发光材料，用于制造发光二极管 (LED)。

Compared with solid scintillators, liquid scintillators have limited capability in dosimetry and radiography due to their relatively low light yields. Here, we report a new generation of highly efficient and low-cost liquid scintillators constructed by surface hybridisation of colloidal metal
