Growth and structural investigations on lead-doped NdMnO3single crystals

Yttrium-doped lead tungstate crystals

In this paper we present results of a study on the yttrium doping in lead tungstate crystals. The crystal growth by modified Bridgman method is described. Results of trace analysis on raw materials and crystals are presented. The segregation coefficient of yttrium ions in lead tungstate crystals was determined. The scintillation emission and longitudinal transmittance spectra, light output, dec...

Investigations on Gel Grown Lead Iodide and Thin Films of Gel Grown Lead Iodide Single Crystals

Observations on Surface Microtopography of gel grown PbI crystals and thin films of gel 2 grown PbI crystals are reported. Initiation of 2 growth layers, interlacing pattern, dendritic growth, symmetry and asymmetry hexagonal arms and natural triangular etch pits were seen. The surface topography, of gel grown PbI crystals and 2 of thin films of gel grown PbI have been related to 2 the growth ...

Growth and Characterization of Doped CaF2 Crystals

Growth of CsI(Tl) crystals doped with Ca and Tm and investigation of its scintillation characteristics

In this work, the growth of CsI(Tl) crystals as gamma detector was performed using vertical Bridgman method with Ca and Tm co-dopants. For evaluation of the growth crystals, X-Ray Diffraction (XRD), photoluminescence and thermoluminescence spectra as well as recorded gamma spectra were employed. In addition, the scintillation properties including energy resolution, scintillation decay time, abs...

Lead-flux Growth of Eu4Ir8As7 Crystals

Single crystals of the new arsenide Eu4Ir8As7 were grown from a lead flux. The structure was refined on the basis of single-crystal X-ray diffractometer data: Ca4Ir8P7 type, P21/m, a = 1311.3(1), b = 408.4(1), c = 1360.3(1) pm, β = 98.45(1)◦, wR2 = 0.0640, 1985 F2 values, 95 variables. The iridium and arsenic atoms in the Eu4Ir8As7 structure build up a complex three-dimensional, covalently bond...
