Effect of ion irradiation on the M-Nitroaniline single crystals

In this report, the modifications in the structural, optical, mechanical, electrical and nonlinear properties of 70 MeV Li3+ and 100 MeV Ag7+ ion irradiated M-Nitroaniline single crystals are studied. The irradiation induced defect structures at the crystal surface which becomes more prominent at higher irradiation fluences, leading to the enhancement in the optical absorption behaviour and the nonlinear property of the irradiated crystals. The mechanism leading to the enhanced nonlinearity and the blue shift of the irradiated M-NA crystals has been discussed.
