The X-ray imaging is a powerful tool used in medical diagnostics, non-destructive material inspection, security checks, nuclear plants and research field. Perovskites is considered as a promising candidate for X-ray detection owning to its remarkably improved sensitivity, low-cost synthesis, detection limit, response time and better special resolution. In this review paper the challenges and future scope of the reported work in the lead based and lead free single and polycrystalline perovskites is studied. Most of the reported results are based on single pixel detection. Hence, it is proposed that an interdisciplinary collaborative work will only facilitate its practical implementation in state-of-the-art X-ray imaging technology.

The series of the glasses with general formula (40-x)Li2O:30B2O3:30Bi2O3:xV2O5, with x = 0, 0.5, 1.0, 1.5 and 2.0 mol% was prepared using conventional quenching technique. The glass transition temperature Tg for these samples were determined from Differential Thermal Analysis. The glass transition temperature increases beyond 0.5 mol%. It was found that the glasses under study consist of randomly connected BO3 & BO4 structural units. The density and molar volume of glasses were found to depend on V2O5 content. Initially the density increases, molar volume and glass transition temperature decrease with the addition of V2O5. This suggests that when V2O5 is added to the glass initially up to 0.5 mol% it may be entering as a modifier. Beyond 0.5 mol% density decreases and molar volume increases as V2O5 goes as former. This reveals the role of V2O5 as a glass network former beyond 0.5 mol%. Optical band gap energy decreases and cut off wavelength increases with increase in V2O5 content.

The effect of Bi 2 O 3 addition on the properties of 30Li 2 O:(70-x)B 2 O 3 :xBi 2 O 3 (0 x 35 mol %) has been studied. Density and molar volume are increasing with Bi 2 O 3 content. The observed decrease in glass transition temperature and optical band gap has been explained on the basis of increase in non bridging oxygen which is supported by infrared spectroscopy. From the optical transmittance spectra it is observed that the cut off wavelength increases with Bi 2 O 3 content which is related to the structural changes.
