A new kind of 5 at% Yb-doped Lu0.5Y0.5PO4 crystals were firstly grown by spontaneously nucleated high-temperature solution method using lead pyrophosphate (Pb2P2O7) as the solvent. The X-ray powder diffraction (XRPD) patterns recorded at room temperature showed the crystals possessed tetragonal xenotime structure. The polarized absorption spectra and the fluorescence spectra of Yb:LuxY1-xPO4 were measured at room temperature, respectively. The results show that Yb:LuxY1-xPO4 mixed crystal will be a promising laser material if the crystal size and quality is further improved.

Highly c-axis oriented hexagonal ZnS nanorod-like crystals were grown on soda-lime glass, glasses covered with transparent conductive oxides (TCOs: ITO and FTO) and silicon wafer substrates via a facile and low-cost spray pyrolysis method. The effect of main technological parameters such as precursors molar ratio and concentration, deposition temperature and substrate type on formation and properties of ZnS nanorods is studied.

Four methods including hydrothermal method, glycol-hydrothermal method, microwave-hydrothermal method and glycol-microwave-hydrothermal method were used to prepare magnesium oxide precursor by the reaction of MgSO4·7H2O with (NH4)2CO3. The glycol-hydrothermal method can create high quality Magnesium Oxide precursor with a high degree of crystallinity, high purity, high aspect ratio, smooth surface, and good dispersibility.
- A method to model the transient performance of high frequency vibration in crystal growth (pages 850–859)
XiaoLong Li, YunZhong Zhu, YuLan Liu and Biao Wang
Article first published online: 10 NOV 2014 | DOI: 10.1002/crat.201400174
A general method to study the transient performance of the high frequency vibration in crystal growth systems is developed. The influences of vibration frequency on the transient fluctuation for temperature and velocity are elucidated. An available approach to control the vibration effect is proposed.
- Structural and mechanical properties of KН2PО4 single crystals with embedded nanoparticles and organic molecules
A. V. Kosinova, M. I. Kolybaeva, O. N. Bezkrovnaya, V. F. Tkachenko, E. V. Grishina, A. N. Levchenko, V. M. Puzikov and I. M. Pritula
Article first published online: 10 NOV 2014 | DOI: 10.1002/crat.201400285
The manuscript is devoted to the microstructure – strength relationship of KDP crystals containing organic molecules and the ones with incorporated TiO2 nanoparticles. It is found that differences in the structure formation mechanism result in the opposite influence of the additives on the mechanical properties and the laser damage threshold of KDP crystal.
