Zn(1鈭?em>x)Fe(x)O(1+0.5x) (x = 0.5-5 mol%) nanoparticles were synthesized by a low temperature solution combustion route. The structural characterization of these nanoparticles by PXRD, SEM and TEM confirmed the phase purity of the samples and indicated a reduction in the particle size with increase in Fe content. A small increase in micro strain in the Fe doped nanocrystals is observed from W-H plots. EPR spectrum exhibits an intense resonance signal with effective g values at g 鈮?#xA0;2.0 with a sextet hyperfine structure (hfs) besides a weak signal at g 鈮?#xA0;4.13. The signal at g 鈮?#xA0;2.0 with a sextet hyperfine structure might be due to manganese impurity where as the resonance signal at g 鈮?#xA0;4.13 is due to iron. The optical band gap Eg was found to decrease with increase of Fe content. Raman spectra exhibit two non-polar optical phonon (E2) modes at low and high frequencies at 100 and 435 cm鈭? in Fe doped samples. These modes broaden and disappear with increase of Fe dopant concentration. TL measurements of 纬-irradiated (1-5 kGy) samples show a main glow peak at 368 掳C at a warming rate of 6.7 掳Cs鈭?. The thermal activation parameters were estimated from Glow peak shape method. The average activation energy was found to be in the range 0.34-2.81 eV.
