Both enhancement effects exhibit strong dependence on the nanoparticle size. Using the example of Ag nanospheres embedded in GaN, we show that strong enhancement can be obtained only for those quantum dots, atoms, or molecules that are originally inefficient in absorbing as well as in emitting optical energy. We then discuss practical limits of enhancement.","PeriodicalId":269220,"journal":{"name":"2009 IEEE LEOS Annual Meeting Conference Proceedings","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125563337","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}
