	1	Synthesis,structure and NIR luminescence properties of Yb^3+ and Bi^3+-activated vanadate GdVO4显示文摘Near-infrared emission of Yb^(3+) and Bi^(3+)-co-doped GdVO_4 vanadate phosphors obtained via the modified Pechini's method was reported. The phase purity and structure of samples were characterized by X-ray powder diffraction(XRD), X-ray energy dispersion spectroscopy(EDS), scanning electron microscopy(SEM), Raman and infrared(IR) spectroscopy. Photoluminescence emission(PL) and excitation(PLE) spectra were recorded and investigated in details. Results indicated that upon near-UV excitation(340 nm) in the(Bi^(3+)-V^(5+)) charge transfer state this phosphor had a strong broad band yellow-green emission(~3P_1→~1S_0) of Bi^(3+) ions and also NIR emission(~2F_(5/2)→~2F_(7/2)) of Yb^(3+) ions in the range of 950–1050 nm, which matched well with the spectral response of the silicon-based solar cells. The decreasing Bi^(3+) emission with increasing Yb^(3+) concentration proved the occurrence of energy transfer from Bi^(3+) to Yb^(3+) ions. Results demonstrated that Yb^(3+) and Bi^(3+)-co-doped GdV O4 vanadate phosphors might act as a NIR down-conversion(DC) solar spectral converter to enhance the efficiency of the silicon-based solar cells.

	2	Laser induced broad band anti-Stokes white emission from LiYbF_4 nanocrystals显示文摘Spectroscopic properties of tetragonal LiYbF_4 nanocrystals under high dense NIR excitation at vacuum condition were investigated. White, broad band emission covering whole visible part of the spectrum from LiYbF_4 nanocrystals was observed. Its intensity strongly depended on the excitation power, excitation wavelength and ambient pressure. Temperature of the nanocrystals under 975 nm excitation was determined as a function of excitation power. Strong photo-induced current was observed from LiYbF_4 pallet. The emission kinetic was analyzed. The mechanism of the anti-Stokes white emission was discussed in terms of the laser-induced charge transfer emission from Yb^(2+) states.
