“…They have observed that after annealing, the optical band gap decreases gradually for the crystallized films while the refractive index increases, and this behavior can be attributed to the transformation from amorphous to crystalline phase and explained in terms of dangling bond model. The thermal annealing effect on the defects structure in γ-irradiated Cd-Zn-Te crystals by photoluminescence method have been explained by Nasieka et al [141]. They have observed that the amplitude of donor bound exciton lines increases after thermal annealing explained by the reconstruction of the initial donor defect structure and the reconstruction process is caused by the transmission of the additional thermal energy which leads to the substantial movement of the radiation induced vacancies and interstitials ions with their further annihilation.…”

The irradiation of nanomaterials with energetic particles has significant effects on the properties of target materials. In addition to the well-known detrimental effects of irradiations, they have also some beneficial effects on the properties of nanomaterials. Irradiation effect can change the morphology of the materials in a controlled manner and tailor their mechanical, structural, optical and electrical properties. Irradiation induced modifications in the properties of nanomaterials can be exploited for many useful applications. With the aim of getting better performance of electronic devices, it is necessary to discuss the irradiation induced changes in the nanomaterials. In order to improve the irradiation hardness of electronic components, it is also crucial to have a fundamental understanding of the impact of the irradiation on the defect states and transport properties of the host material. In the present article, we review some recent advances on the irradiation induced effects on the properties of semiconducting nanomaterials. We have reviewed the effect of different types of irradiations which includes γ-irradiation, electron beam irradiation, laser irradiation, swift heavy ion irradiations, thermal induced, and optical induced irradiations, etc. on the various properties of semiconducting nanomaterials. In addition, the irradiation induced defects are also discussed.
