Background technology
1.5 micron waveband fluorescence can be used for the gain material of fiber amplifier simultaneously because human eye is had security.So rare earth Er
3+The near-infrared fluorescent material of ion doping has application widely aspect medical science and the fiber amplifier.Yet, to compare with crystalline material usually, the luminous efficiency of rare earth ion in glass medium is relatively low, so the normally important selection of laserable material of crystalline material.People such as MC Tan have prepared the adulterated nano Ce F of Er-Yb
3, because Ce can suppress the up-conversion luminescence of Er ionic, so the adulterated nano Ce F of Er-Yb
3Has (the Near infrared-emitting Er-and Yb-Er-doped CeF of near infrared emission efficiently
3Nanoparticles with no visible upconversion, Optics Express, Vol. 17, Issue 18, pp. 15904-15910 (2009)).But crystalline material prepares monocrystalline and the corresponding optical devices preparation cost is high, processing difficulties.Especially for fluorochemical, other compounds are higher relatively for its preparation process, and processing is also difficult more.
In recent years, the researchist proposes to utilize the transparent nano sytull to improve the deficiency of crystalline material.Nano crystalline glass is one type of transparent glass material that contains the nanocrystal medium.In the preparation process, through rare earth ion doped, rare earth ion can enter into nano microcrystalline, and glass has kept the transparency and the workability of height simultaneously.People such as Song utilize Er-Yb phosphate nano sytull, through preparing the ytterbium orthophosphate nano microcrystalline, and Ce
3+Codoped through suppressing Er
3+Thereby up-conversion luminescence realized near infrared emission (the Effects of Ce of 1.5 micron wavebands efficiently
3+On the spectroscopic properties of transparent phosphate glass ceramics co-doped with Er
3+/ Yb
3+, Optics Communications 282 (2009) 2045 – 2048).Yet phosphate glass poor chemical stability and mechanical property are low; Use a large amount of P contained compounds simultaneously; Prepare volatilization easily in the process at high temperature; Component is not easy control, needs segmentation thermal treatment simultaneously and founds and the volatilization that mode reduces phosphorus such as take to add a cover in the process, and therefore preparation is comparatively complicated.
Summary of the invention
