Kapphan","doi":"10.1117/12.475343","DOIUrl":"https://doi.org/10.1117/12.475343","url":null,"abstract":"A theoretical model for two characteristic photoluminescence (PL) bands in SBN, 'green luminescence' and 'red luminescence' is proposed on the basis of the extended photoluminescence experiments in SBN:Cr, and also in SBN:Ce and in nominally pure SBN systems under different conditions. While the RL-band is suggested to be connected with charge transfer vibronic exciton (CTVE) clusters induced by Cr3+ impurities in the Nb-sites, the GL- band is connected with Nb4+ electronic polarons in a new, charge transfer excited states. Here Nb4+ centers are the cores of the CTVE clusters induced by these charged scores. The PL mechanism is the in-cluster CTVE recombination for both bands under discussion. But the CTVE states are quasi-resonantly mixed here with 4T2 states of the Cr3+ core in the RL-band case, and with 5s-states of the Nb4+ core in the GL-band case. The role of excitonic polarons of CTVE nature is also discussed in connection with 'green' luminescence origin in KTaO3 and KNbO3 crystals.","PeriodicalId":312884,"journal":{"name":"Feofilov Symposium on Spectropscopy of Crystals Activated by Rare-Earth and Transition Metal Ions","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123097713","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 spectral properties of Cr3+ ions are researched. The magnitude of emission cross-section at the wavelength of 833 nm corresponding to the maximum of vibronic transition 4T2-4A2 of Cr3+ ion is estimated. The excited state lifetimes at room and liquid nitrogen temperatures are determined. The spectroscopic investigations show that impurity Cr3+ ions in KTP crystal are placed in positions with weak crystal field: Dq equals 1507 cm-1, B equals 652 cm-1, C equals 2800 cm-1. The configuration diagram model with one excited state is discussed.
