HCl＋Xe掺杂CO矩阵晶体中Xe＋2Cl－电子态跃迁

Electronic Relaxation of the Exciplex in HCl+Xe Doped Crystalline CO

报道ＨＣｌ＋Ｘｅ掺杂ＣＯ矩阵晶体中，在３０８ｎｍ激光的激发下，首次观测到准分子Ｘｅ＋２Ｃｌ－的特征辐射荧光谱。双光子诱导电荷转移合作吸收反应：Ｘｅ＋ＨＣｌ＋２ｈν→αＸｅ＋（ＨＣｌ）－中，双光子吸收截面大于５×１０－４２ｃｍ４ｓ［６］。

The emission spectrum of Xe + 2Cl - in HCl+Xe doped crystalline CO, excited by 308 nm laser, are firstly observated. The cooperative charge transfer absorptions: Xe+HCl+ 2hν → α  is demonstrated, and the four body, two photon absorption cross section at 308 nm is ≥5×10 -42 cm 4 s.
