Effect of γ-irradiation on structure and properties of Nd 3+ doped Perovskite

Recent Development of Halide Perovskite Materials and Devices for Ionizing Radiation Detection

“…As compared to the single crystals and compressed wafers, the fabrication methods for polycrystalline perovskite films have been well-developed in numerous solar cell studies. − Recently, the application of perovskite films for radiation detection has also been explored by several groups. , As early as 2015, Yakunin et al. reported a solution-processable lead halide perovskite polycrystalline radiation detector for the first time .…”

Gamma-ray dose threshold for MAPbI3 solar cells

“…11 To imitate space radiation on the Earth, various facilities with different particles and energies are used: protons, 12,13 electrons, 2,14 X-rays 10,15,16 and gamma-rays. 5,[7][8][9][17][18][19][20][21][22] Normally, electron irradiation is used due to the vast availability of electron beam setups. However, Ahmad R. Kirmani suggested that proton irradiation with low energies up to 1 MeV is a more accurate way to estimate the radiation hardness of perovskites.…”

Investigating the impact of gamma radiation on structural and optical properties of Eu3+ doped rare-earth hafnate pyrochlore nanocrystals

“…Most of the work in these areas is focused on irradiating the materials with gamma radiation, observing the changes in optical properties, and investigating radiation stability, etc. Intensive work has been performed to explore the photoluminescent properties of a variety of materials which have been exposed to γ-rays, such as bismuth/erbium co-doped silica fibers [5], graphene and CdTe/CdS colloidal quantum dots [6][7][8], ZnO and SnO 2 nanoparticles [9,10], gadolinium oxysulfide nanophosphors (Gd 2 O 2 S-nanoparticles) [11], porous silicon [12], NdPO 4 [13] and doped phosphor and glass materials [14][15][16]. There exists an interesting class of inorganic materials with the A 2 B 2 O 7 composition, which exists in two structural variations: the ordered pyrochlore (OP) with Fd-3m space group and the disordered fluorite (DF) having Fm-3m space group.…”
