Effective role of CaO/PO ratio on SiO-CaO-PO glass system.

In the present work, the effect of the CaO/PO ratio on the composition of sol-gel synthesized 58SiO-(19 - )PO-(23 + )CaO ( = 0, 5, 10 and 15 mol%) glass samples was studied. Further, the effect of NBO/BO ratio on hydroxy carbonated apatite layer (HCA) forming ability based on dissolution behavior in simulated body fluid (SBF) solution was also investigated. CaO/PO ratios of synthesized glass samples were 1.

Electron irradiation effects on optical properties of semiorganic antimony thiourea tetra chloride single crystals.

Antimony thiourea tetra chloride single crystals were grown by solution growth technique at room temperature. The UV-visible, fourier transform infrared and fluorescence spectra were recorded and electron irradiation effects on these properties were studied. The optical absorption edge of the UV-visible spectrum slightly shifts towards longer wavelength with the increase of irradiation dose.
