Visible-blind UV photodetectors using a polymer/ZnO nanocomposite thin film

CuBi2O4nanocrystals integrated with polyaniline nanobelt arrays for weak light photomultiplication type photodetector

“…Numerous people are becoming interested in creating panchromatic, ultraviolet, near-infrared, and color-selective photodetectors. 45,46 Due to their low background noise and short response times, photodiode type nanohybrid photodetectors are excellent for practical applications such as optical communication, remote control, and image sensing. The fundamental issue with conventional device structures is their inability to achieve extraordinarily high EQE in low-light situations.…”

Self-powered ZnO-based pyro-phototronic photodetectors: impact of heterointerfaces and parametric studies

“…The combination of interfacial effects resulted in an improvement of the response time associated with UV PDs, where a significant reduction in the response times of ZnO-based PDs was shown. 78,79 Various reports are available on implementing the p-n heterojunction as a hard substrate utilizing the pyro-phototronic effect, which imparts a rapid response rate and an improved photoresponsivity while utilizing primary and secondary pyroelectric effects. 66,72,73 The pyro-phototronic working principle shown in Fig.…”

Polarization detection of ultraviolet light using ZnO microwires

“…ZnO, with a direct band gap of approximately 3.37 eV, can effectively absorb UV light but not visible light; therefore, it is an ideal material for UV photoelectric devices 4 – 10 To date, various ZnO heterostructures for use as photodetectors have been constructed, such as p-Si nanowire/ZnO, 11 BeMgZnO/ZnO, 12 ZnO−SnO2, 13 ZnO/graphene, 14 and Cu3(HHTP)2 c-MOF/ZnO heterostructures 15 .
