Triglycine Sulphate (TGS) [(NH2CH2COOH)3H2SO4] is one of the most useful ferroelectric material which finds wide applications as room temperature detectors and in the fabrication of capacitors, transducers, medical vidicons and sensors etc. In this work, an attempt has been made to introduce some organic and inorganic acids such as nitric acid, picric acid, percholoric acid and salicylic acid separately into TGS crystals as admixtures to modify their physical and chemical properties. Single crystals were grown by slow evaporation technique at room temperature. Density was measured by using the…mehr

Produktbeschreibung
Triglycine Sulphate (TGS) [(NH2CH2COOH)3H2SO4] is one of the most useful ferroelectric material which finds wide applications as room temperature detectors and in the fabrication of capacitors, transducers, medical vidicons and sensors etc. In this work, an attempt has been made to introduce some organic and inorganic acids such as nitric acid, picric acid, percholoric acid and salicylic acid separately into TGS crystals as admixtures to modify their physical and chemical properties. Single crystals were grown by slow evaporation technique at room temperature. Density was measured by using the floatation technique and Energy dispersive X-ray spectra were recorded to understand the chemical composition of the grown crystals. Optical behaviour of the grown crystals was studied by UV-visible transmission spectral analysis and linear optical constants such as reflectance, extinction coefficient, refractive index, band gap of the grown crystals were determined. Thermogravimetric (TG) and differential thermal analysis (DTA) were carried out to understand the thermal stability of the grown crystals.
