%X We report for the first time a non-template based facile growth of hexagonal (¦Â) AgI nanorods and nanoplates easily fabricated by rf magnetron sputtering on Ag/Sn bilayers upon controlled iodination. The structural and morphological evolution of the ¦Â-AgI nanostructures is cha-racterized by X-Ray Diffraction, Atomic Force Microscopy and optical spectroscopy. Sput-tering induced disorder in precursor Ag films, high external stress and high defect concentra-tions at the Sn-AgI interface particularly facili-tates the development of layered hexagonal structure of ¦Â-AgI nanostructures. Extremely sensitive room temperature optical absorbance involving evolution of W1,2 and W3 exciton tran-sitions and emission spectra involving phonon replica corroborate the formation of ¦Â-AgI na-nostructures with high defect concentrations, are aimed at improving the efficiency of photo-graphic process and looking at microelec-trodic and optoelectronic applications.
