ZnO nanocrystals (ZnO-nc) have a bandgp of 3.37eV and a large exciton binding energy of 60meV, which make them attractive material for devices which operate in the ultraviolet (UV)-blue region of the electromagnetic spectrum [1]. Consequently, ZnO-nc have also been used as sensitizers to excite the rare-earth(RE) ions such as Ce3+, Er3+, Ho3+, Nd3+, Tm3+, Dy3+, Eu3+ and Tb3+ [2–9] which absorb the UV-blue emission from the ZnO-nc and in turn emits their own light in the visible or infra-red wavelengths. ZnO-nc have been used as sensitizer mainly due to its large absorption cross-section and broad excitation spectrum [10] compared to the RE ions. Recently, our group has published a detailed study on the energy transfer mechanism from ZnO-nc to Eu3+ ions [11], which results in strong red emission from Eu3+ at 614nm. In the above mentioned study, the contribution of the various ZnO-nc emission centres, which has been identified to consist of seven de-excitation centres [12], in the energy transfer process to the Eu3+ ions was investigated. In this work, we continue to study the energy transfer contribution from the various ZnO-nc emission centres to the Tb3+ ions embedded in SiO2, based on the spectral overlap of ZnO-nc emission and Tb3+ ions excitation. The results from this study, along with our previous results on the energy transfer contribution from the various ZnO-nc emission centres to the Eu3+ embedded in SiO<inf>2</inf> matrix [11], will help in fabricating proficient red, blue, green and even white light sources by combining the blue, green and red emissions from ZnO-nc, Tb3+ and Eu3+, respectively which can be used in various photonic applications.","PeriodicalId":396459,"journal":{"name":"2016 IEEE Photonics Conference (IPC)","volume":"117 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124566346","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}

Such resonances result in great enhancements of ionic second-order nonlinearities [1]. For LiNbO3, dominant element of the ionic second-order nonlinear susceptibility tensor coefficients d33 at 7.5 THz is a factor of about 50 larger than its electronic nonlinearity. Semiconductor materials such as GaAs, GaP, and GaN all exhibit these huge enhancements of the ionic second-order nonlinear coefficients by their polariton resonances. Obviously, one can exploit these huge nonlinear coefficients for greatly enhancing efficiencies of nonlinear parametric processes. The drawback, though, is extremely large absorption being companied with the huge nonlinearities within these strong resonances. Although sum-frequency generation [2], second-harmonic generation [3,4], and generation of THz [5,6], far-IR [7] and mid-IR [8] were investigated near the polariton resonances, the extremely low conversion efficiencies due to extremely large absorption and phase mismatch [2,7] made these nonlinear effects have no practical value.","PeriodicalId":396459,"journal":{"name":"2016 IEEE Photonics Conference (IPC)","volume":"29 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122288710","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}
