The correlations between improvement of light yield in mixed crystals, and the ratios of ionic radii and atomic weights of the substituted atoms, as well as the bandgap difference between the components of mixed crystal, have been analyzed. It is presumed that non-monotonous dependence of light yield on components ratio in mixed scintillators is called by modulation of energy structure and limitation of carrier migration length due to spatial inhomogeneity in crystal. Phenomenological approach to prediction of light yield in mixed scintillation crystals has been proposed.","PeriodicalId":142377,"journal":{"name":"International Conference on Oxide Materials for Electronic Engineering - fabrication, properties and applications (OMEE-2014)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130041803","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}
