英文摘要	研究了掺铒的纳米相氟氧化物玻璃陶瓷(Er(3):FOV)的红外量子剪裁现象,测量了红外和可见的Er(3):FOV的荧光光谱.结果发现光激发2H(11/2)能级的4I(13/2)→4I_(15/2)荧光跃迁的近似量子剪裁效率已达约186.28%.; The article reports the infrared quantum cutting phenomenon of the Er-doped nanophase oxyfluoride vitroceramics (Er(3) : FOV). The infrared and visible fluorescence spectra of Er(3) : FOV are measured carefully. It is found that the approximate quantum cutting efficiency of the 1543.0 nm (4)I(13/2) -> (4)I(15/2) fluorescence, when the (2)H(11/2) levels are excited, is about 186. 28%. The relative nonradiative relaxation rate and spontaneous emission rate and energy transfer rate are calculated. The relative energy transfer dynamics is analyzed. It is found that the {(2)H(11/2) -> (4)I(9/2), (4)I(15/2) -> (4)I(13/2)} energy transfer channel, with the rate of 371000 s(-1), is the main reason for (2)H(11/2) energy level to have high quantum cutting efficiency. To our best knowledge, the present article for the first time reports Er(3) : FOV to have an effective three-photon infrared quantum cutting excited by visible light and a four-photon infrared quantum cutting excited by near-violet light.; 国家自然科学基金; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000280168700106&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; SCI(E); 中文核心期刊要目总览(PKU); 中国科技核心期刊(ISTIC); 中国科学引文数据库(CSCD); 5; 7; 5091-5099; 59
