Ultraviolet radiation detection by barium titanate thin films grown by sol–gel hydrothermal method

Coupling of photoelectric and triboelectric effects as an effective approach for PZT-based high-performance self-powered ultraviolet photodetector

“…2e shows the current sharply decreases by more than 90 % within a half period of 50 ms. Therefore, the response time of the UV-SPPD is found to be less than 50 ms, which is superior to the results of previous reports by Sharma et al [32] and Zomorrodian et al [33] Fig. 2f shows the photocurrent spectral response of the UV-SPPD at 254 nm, 365 nm and 400 nm with an incident intensity of 100 μW cm -2 , respectively.…”

Self‐Polarized BaTiO3 for Greatly Enhanced Performance of ZnO UV Photodetector by Regulating the Distribution of Electron Concentration

“…These results revealed that the as‐prepared BTO‐ZnO film can act as a promising candidate for transparent UV detectors due to its excellent selectivity in UV absorption and high transmittance in the visible region. As shown in Figure S2a,b, Supporting Information, the bandgaps of as‐prepared ZnO and BTO particles films are estimated to be 3.28 and 3.52 eV by the Tauc plots according to the UV–vis absorbance spectroscopy, respectively …”

Novel UV Sensing and Photocatalytic Properties of DyCoO3

“…Therefore, the development of materials able to detect UV radiation is worth investigation. The photodetection properties of perovskite oxides have been previously investigated; 2 Journal of Sensors however, they have been limited to few compounds like BaTiO 3 , SrTiO 3 , LiNbO 3, and LiTaO 3 [19][20][21][22]. In the case of cobalt-based perovskites, Liu et al studied the detection of visible light using nanostructured LaCoO 3 thin films, grown epitaxially on SrTiO 3 substrates [23].…”
