英文摘要	通过实验分别测得了掺杂Ho3+(0.5mol%)的氟氧化物玻璃(FOG)样品和掺杂Ho3+(0.5mol%)的氟氧化物玻璃陶瓷(FOV)样品的吸收光谱,根据Jubb-Ofelt理论拟合出两种材料强度三参量Ω2,4,6,并且分析了两种材料在强度参量上产生差异的可能原因。再由拟合得到的强度参量值计算出了各激发态之间的振子强度,自发辐射跃迁速率,荧光分支比和积分发射截面等光谱学参量,并且对两种材料的各参量进行了对比分析,Ho3+在FOV和在FOG中的振子强度相差不多,与在YAlO3中大致相同,比在钛酸铝氟化物玻璃(lead borale titanale aluminium fluoride,LBT...; In the present paper, the absorption spectra of Ho3+ (0.5 mol%)-doped oxyfluoride glass (FOG) sample and Ho3+ (0.5 mol%)-doped oxyfluoride vitroceramics (FOV) sample were measured through experiment. The authors calculated the intensity parameters Omega(2,4,6) of the two materials according to J-O theory, and analyzed the possible reason for the difference between the two materials on the intensity parameters. After that the authors calculated oscillator strength, spontaneous radiative transition rate, branching ratio and integrated emission cross section and some other spectroscopic parameters of several excited states and then made a comparative analysis of the two materials based on these spectroscopic parameters. The authors found that the oscillator strength of trivalent holmium iron in FOV is about the same with the oscillator strength in YAlO3 and is similar to oscillator strength in FOG, while slightly larger than in that LBTAF and much larger than that in LaF3 and ZBLAN. By analyzing the calculated spectroscopic parameters, it can be found that some transitions, especially I-5(7) -> I-5(8), F-5(5) -> I-5(8) etc., have a relatively large oscillator strengths(larger than 10(-6)) and large integrated emission cross sections(larger than 10(-18) cm). These transitions have the conditions to form laser passages, so they are worth a lot of attention. At last, application prospects of several strong luminescence transitions were concluded.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000321408100002&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; SCI(E); EI; 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); 0; 07; 1734-1738; 33
