| 摘 要： | 采用斯塔克光谱技术研究了酞菁锡多晶薄膜中的激子跃迁和电荷转移。观察到一系列分子间电荷转移所形成的双分子激子谱带，显示了斯塔克光谱技术在探测淹没于弗伦克尔激子带下面的微弱电荷转移跃迁方面具有独特的优点和很高的灵敏度。

| Abstract: | Stark spectroscopy(electroreflection spectroscopy) technique was applied to investigate the exciton transitions and charge transfer excitations in a Tin phthalocyanine(SnPc) polycrystalline film. A series of intermolecular charge transfer(CT) spectral bands was observed, which demonstrated the unique advantage and high sensibility of Stark spectroscopy in revealing weak CT transitions buried under strong Frenkel exciton bands. Photovoltaic action spectrum was measured for an ITO/SnPc/Al sandwiched device. The role that CT excitons played in photoconductivity was discussed. |
