Electronic absorption spectrum of the polymer exhibits a Q-band peak positioned at about 736 nm, which is obviously red shifted compared with 2, 9, 16, 23-tetra-carboxyl manganese(II) phthalocyanine (TCMnPc). PPE-MnPc films were prepared by dip-coating technology. Photoconductivity of PPE-MnPc films was characterized by current-voltage measurement. At bias voltage of 20 V, photoconductivity of the film was 6.8×10-9 S and dark conductivity was 7.5 ×10-10 S. The electrical conductivity of PPE-MnPc films under irradiation was nine times higher than that in the dark, which indicated that PPE-MnPc had a good photovoltaic response.","PeriodicalId":316559,"journal":{"name":"International Conference on Thin Film Physics and Applications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129984000","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Ion beam sputtering deposition technique was used to manufacture reflection coating for three-wavelengths and a LAMBDA900 spectrophotometer was used to analysis the reflectance at three wavelengths which achieved the design requirements.

The temperature coefficient of resistance (TCR) of TiW alloy film is an important parameter influencing the characteristic, so it is very necessary to study the effect of TiW alloy films deposition parameters on TCR. In this paper, TiW alloy films were deposited by DC magnetron sputtering on ordinary glass, and the target is high pure TiW alloy material ((Ti:W)atom=3:7), the working gas is Ar. The square resistance of TiW alloy films under the different temperature was measured using four-point probe meter, and TCR was calculated according to the measurement curve. The influence of working pressure, Ar flow rate and sputtering current on the TCR of TiW alloy films was investigated. After studying, the best process parameters were obtained, that are, sputtering current 0.32A, working pressure 0.8Pa, and Ar flow rate 60sccm. Under these condition, TCR of TiW alloy films is 2‰/K. The measurement results indicate that the time stability of TiW alloy films is excellent.","PeriodicalId":316559,"journal":{"name":"International Conference on Thin Film Physics and Applications","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125313166","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
