SPECTRAL, MECHANICAL AND LINEAR OPTICAL STUDIES OF SODIUM HYDROGEN CARBONATE DOPED SULPHAMIC ACID SINGLE CRYSTALS

Abstract

Sodium hydrogen carbonate doped sulphamic acid crystals were grown by solution method. The grown crystals are colorless and transparent and they were subjected to various studies for characterization. From the characterization studies, it is confirmed that the grown crystal are with the enhancement of properties compared to the properties of the pure sample crystal. The unit cell parameters of the grown crystal were confirmed by single crystal X-ray diffraction. Good crystalline nature of the grown material is confirmed by the appearance of sharp peaks. The functional groups of the grown crystal were found by FTIR study. UV- Visible transmittance is recorded for the sample to analyze the transparency of the grown crystal. The value of band gap energy was found to be 4.8 eV. The Hardness studies reveal that the grown crystal belongs to soft category.
