Tris-(8-oxyquinoline) aluminum (Alq3) was one of the first compounds which demonstrated high efficient green electroluminescence and to the moment it is still used as emission and electron transport material in OLED. Alq3 is known to exist in several polymorphs with photoluminescence (PL) maximum varied from 537 to 481 nm. One of main problem of OLED technology consists in a high cost of organic materials. An attempt to use organic-inorganic hybrid materials for a creation of a novel thin film emission device has not been very successful yet. But the investigation of hybrid material (HM) based on B2O3 glass matrix and Alq3 as phosphor agent showed that there were observed a significant shift of luminescent peak to short waves after bulk HM annealing. The change in the luminescence spectrum can was explained by the polymorph and/or conformation transitions in Alq3 in the crystal field of the matrix.","PeriodicalId":191027,"journal":{"name":"2014 International Conference Laser Optics","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125235268","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 clockwork can ensure ultra-low relative instability (less than 10-17) of generated frequencies provided that a proper optical frequency standard is applied.
