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. The fluorescence quantum yield is decreased for electron irradiated antimony thiourea tetra chloride crystals. The presence of functional group of the as-grown and electron irradiated complex was confirmed by fourier transform infrared spectral study.

Electron irradiation effects on optical properties of antimony thiourea tetra chloride single crystals grown by solution technique were studied. The optical absorption edge of the UV–visible spectrum shows slight shift towards longer wavelength with the increase of irradiation. The fluorescence quantum yield is high for as-grown crystals and the C–N stretching frequency was found to increase with irradiation.Figure optionsDownload as PowerPoint slideHighlights
