Growth and characterization of pure and lithium doped strontium tartrate tetrahydrate crystals by solution-gel technique

Abstract

The effect of lithium ion as dopant on the size and transparency of strontium tartrate tetrahydrate (SrC 4 H 4 O 6 ⋅4H 2 O) crystals are presented in this paper. Growth of single crystals of undoped and lithium doped strontium tartrate tetrahydrate by controlled diffusion of strontium nitrate into the gel charged with tartaric acid at room temperature are narrated. The lithium ion enhances the size and transparency of the doped crystals. The crystal structure of the compound was confirmed by X-ray diffractometry and dopant concentration with ICP-atomic emission spectrometer system. Thermal decomposition of the grown crystals is investigated by TGA and DTA studies. The FTIR spectra of pure and doped crystals are recorded and analysed. Kurtz powder technique has been used to test SHG efficiency of the crystals.

Growth, Laser Raman, Thermal, Edax and Photoluminescence Studies of Pure and Calcium Doped Zinc Hydrogen Phosphate Crystals Using Single Diffusion Technique

“…In conventional growth, pure ZnHPO4 crystals were accomplished at 40ºC in a constant temperature bath have been already reported [8]. In this present work, we have attempted to grow pure and calcium doped ZnHPO4 crystals by single diffusion technique at room temperature [9][10][11][12][13]. The purpose of the present article is to report for the first time the growth of pure and calcium doped single crystals in silica gel medium by using single diffusion technique at room temperature.…”
