A study on the growth of Yb:YVO4 single crystal

Synthesis and homogeneity range of Yb8−xYxV2O17 in the Yb8V2O17–Y8V2O17 system

“…Yttrium vanadates(V) doped with rare earth metals have been for a few decades the subject of interest because of their unique and attractive physicochemical properties and have been applied in many branches of industry [1][2][3][4][5][6][7][8][9][10][11][12][13]. Yttrium orthovanadates(V) doped with Nd 3?…”

“…, Er 3? or Yb 3? ions make interesting laser materials employed in lasers used in medicine or electronic industry [1][2][3][4][5][6][7]. YVO 4 3? ions has been applied as a luminophore or for production of plasma displays, electroluminescent diodes or fluorescence lamps [8][9][10][11][12][13]. Many scientific reports have been devoted to yttrium or ytterbium orthovanadates(V) [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18], but much less attention has been paid to other vanadates (V) [19][20][21][22].…”

Effect of Yb doping on the crystal structure, polarization dependent optical absorption and photoluminescence of Yb:YVO4 single crystal grown by optical floating zone technique

“…As per the study by Zhong et al [10] on 0.11 and 0.26 at.% Yb doped sample they exhibited the contraction of lattice. On the other hand study by Chen et al [5] on the higher Yb doped sample i.e., for 4.8, 9.5 and 18.1 at.% Yb, has shown that the lattice shows shrinkage at doping concentration of 9.5 and 18.1 at.%. Our systematic study on the whole range of the doping concentration clearly revealed that the lattice volume is indeed not affected at lower doping concentrations and exhibits slight systematic decrease only at higher doping concentration above 2.94 at.%.…”

“…In recent years, crystals doped with trivalent ytterbium ions (Yb 3þ ) have been of great interest as directly diode-pumped laser materials with emission around 1 mm. As a rare-earth ion with the quasi-three level scheme, Yb 3þ offers important advantages such as high efficiency in energy conversion, long fluorescence lifetime and low quantum defect between the pump and the laser wavelengths [5]. Also, Yb has wide solubility in YVO 4 which makes it possible to have high dopant concentration.…”

“…Further there are some ambiguities on the effect of doping concentration on the lattice parameter. For example, while Zhong et al [10] reported that the lattice contracts at doping concentration as low as 0.11 at.%, Chen et al [5] had concluded that the lattice volume is unchanged even at 4.8 at.% of doping.…”
