AbstractAbstract
[en] The objective of the present work is to study photoluminescence (PL), Time resolved PL (TRPL) and Electron spin resonance (ESR) of combustion and sol-gel derived 100 MeV swift Ni"7"+ irradiated Y_2O_3:Tb"3"+ nanophosphors with fluence 1 x 10"1"0 - 3 x 10"1"2 ions cm"-"2. The formation of compounds was confirmed by the X-ray diffraction (XRD), Fourier Transform Infrared spectroscopy (FTIR) and Raman Spectroscopy. XRD patterns confirm cubic phase with decrease in crystallite size after swift heavy ion (SHI) irradiation. TRPL of SHI irradiated sample showed enhanced life time decay. Also, SHI irradiated Tb doped Y_2O_3 showed enhanced green emission intensity, life time and low phonon energy
