  NaTiOPO₄and KTiOPO₄at 110K

  摘要：

  The title compounds, sodium titanyl phosphate and potassium titanyl phosphate, are isostructural, belonging to a family of compounds with interesting non-linear optical properties. The effect of substitution of K by Na has been analysed by X-ray diffraction at 110 K. The substitution does not modify the geometry of the phosphate groups; however, the Ti-O coordination distances are changed, as well as the relative orientation of the Ti and P polyhedra.

  Synthesis and sintering of KTiOPO4, via mechanochemical mixing route

  摘要：

  KTiOPO4 (KTP) powders have been synthesized by a solid-solid reaction method from two series of starting reagents activated mechanochemically (A,KH2PO4+TiO2; B,KNO3+TiO2+NH4H2PO4). The formation mechanism of KTP crystal is discussed on the basis of the evolution of the crystal phase detected by X-ray diffraction and IR absorption peak measurements on powders calcined at various temperatures. The sintering behaviour of the calcined powders has been investigated by density and weight loss measurements and microstructure observations. The final sinterability of series B is superior to that of series A at higher temperatures; the maximum density of the former has been obtained as 93% of the theoretical density.

  Single crystals of KTi1 − x Zr x OPO4 (0.001 < x < 0.044) solid solutions were grown, and their properties were studied. The results indicate that Zr doping has little effect on the ferroelectric transition temperature of the material but markedly reduces its low-temperature conductivity. Moreover, the nonlinear optical susceptibility of the solid solutions exceeds that of KTiOPO4 by more than a factor of 2.

  Abstract The compound KTiOPO 4 shows an extremely short wavelength titanate emission (390 nm) which is quenched at about 100 K. This luminescence is discussed in terms of a self-trapped excition which becomes mobile at higher temperatures. Comparison with other titanates is made. The linear titanate chain in KTiOPO 4 must be rather covalent. In Cs 2 WO 2 Cl 4 we observed an extremely long wavelength

  摘要 化合物 KTiOPO 4 显示出极短波长的钛酸盐发射 (390 nm)，在约 100 K 时淬灭。根据在较高温度下变得可移动的自陷激发来讨论这种发光。与其他钛酸盐进行比较。KTiOPO 4 中的线性钛酸酯链必须相当共价。在Cs 2 WO 2 Cl 4 中，我们观察到极长波长的钨酸盐发射。与相关钨酸盐进行了比较。在Cs 2 WO 2 Cl 4 中，氯钨酸盐基团完全分离。这种发光的低淬灭温度与 KTiOPO 4 的来源不同。

  A series of novel fluorotitanophosphates with a general formula (NH4)xK4 - x[Ti2PO4F9] (x = 0, 0.70, 1.00, 1.25, named as 1, 2, 3, and 4 respectively) have been synthesized under hydrothermal conditions. Their structures were determined by X-ray single-crystal diffraction technique, which show that all of the phases in this series contain an idental anionic fluorotitanophosphate chain, consisting of
