Growth, Optical and Electrical Properties of zinc tris (thiourea) sulphate (ZTS) Single Crystals

Abstract

Single crystals of Zinc Tris (thiourea) Sulphate (ZTS) exhibiting high transparency were grown by slow evaporation technique. Single crystal X-ray diffraction analysis reveals that the crystal belongs to orthorhombic system. The optical absorption study reveals the transparency of the crystal and is noticed in the entire visible region and the cut-off wavelength has been found to be 270 nm. The optical band gap was found to be at 3.55 eV. The dependence of extinction co-efficient (K) and the refractive index (n) on the wavelength have been observed. The electrical properties of the grown crystal have also been studied using the Cole-Cole plot.

Influence of cobalt-doping on the optical properties of zinc tris–thiourea sulfate (ZTS) single crystal

“…The value of E g for pure ZTS crystal (3.89 eV) is in good agreement with that reported in previous works [19][20][21]. Table 1 shows that E g decreases as Co 2+ concentration increased.…”

“…The crystal growth and characterization of ZTS crystal have been studied [13][14][15][16]. Since ZTS crystal is a promising NLO material, its optical properties were the subject of numerous articles [17][18][19][20][21][22].…”

Synthesis and Characterization of a NLO crystal - bis (thiourea) zinc sulphate doped with L-malic acid

“…Growth of bulk single crystals of these materials has been a subject of perennial concern to enable them to be useful for device applications. Some examples of semiorganic NLO materials are zin ctris (thiourea) sulphate (ZTS) [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25], bis (thiourea) cadmium chloride (BTCC), zinc thiourea chloride (ZTC) and copper thiourea chloride (CTC). In the present work, the physical, structural, thermal, dielectric and piezo-electric, NLO properties of LMBTZS crystal was studied.…”
