By measuring the absorption spectrum of PVA with CdS, we could determine the radius of QDs. We confirm that as it increasing the mole ratio (CdCl2/RSH) in the mixture, the mean radius of the QDs decreased and the band gap energy increased. When added the RSH, absorption peak energy was 3.67eV and without the RSH it was 3.20 eV. The radius was 18 A with the RSH and it was 23 A without the RSH. As a result of comparing the low temperature absorption spectrum line with the normal temperature absorption spectrum line, the intensity of absorption was increased and the absorption line moved to the long wave.","PeriodicalId":384775,"journal":{"name":"2007 Conference on Lasers and Electro-Optics - Pacific Rim","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127635291","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}
