Up-conversion of Er3＋/yb3＋ co-doped transparent glass-ceramics containing Ba2LaF7 nanocrystals

The up-conversion of Er3+/Yb3+co-doped transparent glass-ceramics 50SiO2-10AlF3-5TiO2-30BaF2-4LaF3-0.5ErF3-0.5YbF3 containing Ba2 LaF7 nanocrystals under the changing of heat treatment temperature and time were investigated.The Ba2 LaF7 nanocrystals precipitated from the glass matrix was confirmed by X-ray diffraction(XRD).The structural investigation carried out by XRD and transmission electron microscopy(TEM) evidenced the formation of cubic Ba2 LaF7 nanocrystals with crystal size of about 14 nm.Comparing with the samples before heat treatment,the high efficiency up-conversion emission of Er3+/Yb3+co-doped samples was observed in the glass-ceramics under 980 nm laser diode excitation.The increase in red emission intensity bands was stronger than the green bands when the crystal size increased.The mechanism for the up-conversion process in the glass-ceramics and the reasons for the increase of Er3+/Yb3+co-doped up-conversion intensity after heat treatment were discussed.

Er~（3＋）/Yb~（3＋）共掺氟磷酸钙纳米微晶玻璃的高效近红外发光性质研究（英文）

本文制备了Er3＋/Yb3＋共掺的透明氟磷酸钙纳米微晶玻璃,并对其近红外发光性质进行了研究。样品经过热处理后,经X射线衍射和透射电镜测试发现：玻璃基质中均匀地析出了20 nm左右的Ca5（PO4）3F晶体,并且稀土离子进入到了析出的纳米晶相中.同热处理之前的样品相比,在808 nm和980 nm激光的激发下,Er3＋/Yb3＋共掺的微晶玻璃在1.54μm处产生很强的近红外发光,其半高宽高达75 nm.另外,我们对微晶玻璃的近红外发光与Er3＋和Yb3＋浓度的关系进行了研究.由于其具有高效的近红外发光,表明Er3＋/Yb3＋共掺的氟磷酸钙纳米微晶玻璃是一种潜在的激光和光放大材料.

Recent progress on upconversion luminescence enhancement in rare-earth doped transparent glass-ceramics

The upconversion(UC) of the rare earth doped glass-ceramics has been extensively investigated due to their potential applications in many fields, such as color display, high density memories, optical data storage, sensor and energy solar cell, etc. Many series of them, especially the oxyfluorides glasses containing Ba2 LaF 7 nanocrystals were studied in this review work, due to the thermal and mechanical toughness, high optical transmittance from the ultraviolet to the infrared regions, and a low nonlinear refractive index compared to the other commercial laser glasses. Moreover, the energy transfer(ET) between the rare earth ions and transition metals plays an important role in the upconversion process. The cooperative ET has been researched very activly in UC glasses due to applications in the fields of solar cells, such as in the Er/Yb, Tm/Yb, Tb/Yb, Tb/Er/Yb and Tm/Er/Yb couples. The present article reviews on the recent progress made on:(i) upconversion materials with fluoride microcrystals in glasses and the mechanisms involved, including the UC in double and tri-dopant RE ions activated fluoride microcrystal, energy transfer process; and(ii) the effect of the metal Mn and nanoparticles of Au, Ag, Cu on the enhancement of UC emissions. Discussions have also been made on materials, material synthesis, the structural and emission properties of glass-ceramics. Additionally, the conversion efficiency is still a challenge for the spectra conversion materials and application; challenge and future advances have also been demonstrated.
