| 摘 要： | 用接触电位差(CPD)方法研究了导电聚合物MEH-PPV薄膜的光电特性，测得MEH-PPV的能隙为2．1eV，表面功函数为4．7-4．8eV，是p型导电材料，同时研究了不同铸膜溶剂对薄膜光电特性的影响，测得由不含芳环的四氢呋喃为溶剂制得的薄膜表面功函数比由含芳环的氯苯为溶剂制得的薄膜低0．15eV。

| Abstract: | The photoelectric characteristics of conducting polymer MEH-PPV thin film were studied using contact potential difference (CPD) method. The energy gap and the surface work function (SWF) of MEH-PPV thin film were determined as 2.1 eV and 4.7-4.8 eV, respectively; and the p-type conducting characteristic of film was determined, too. Meanwhile the influence of different coating solvents on photoelectric characteristic of thin film was investigated, and the result indicates that the SWF of film coated from tetrahydrofuran (THF) is 0.15 eV lower than that from chlorobenzne (CB) solution. |
