Studies on Ag8+ and Li4+ ions irradiated LAHCl single crystals

Semi-organic single crystals of LAHCl were grown by unidirectional solution growth method. The grown single crystals were subjected to Ag8+ and Li4+ ions irradiation of energy 100 MeV and 50 MeV, respectively. Breaking of bonds in the irradiated LAHCl molecules and the lattice deformations are analyzed by Fourier transform infrared spectroscopy and X-ray diffraction studies, respectively. The modifications induced by ion irradiation in dielectric, mechanical stability and nonlinear optical property are studied at different ion fluence.

► LAHCl single crystals were irradiated with Ag8+ and Li4+ ions for the first time.
► Dielectric constant and hardness of the LAHCl increased at low ion fluence.
► Increased dielectric constant in irradiated LAHCl may enhance the electro-optic coefficient.
► The difference in effect of Ag8+ and Li4+ on physical properties LAHCl was also discussed.
