High-performance metal–semiconductor–metal UV photodetector based on spray deposited ZnO thin films

ZnO based visible–blind UV photodetector by spray pyrolysis

“…In our previous work, we have studied the significance of the substrate temperature on the structural and morphological properties of the ZnO thin film prepared by spray pyrolysis method and also demonstrated the role of crystallinity on the UV sensing properties of the ZnO based MSM photodetectors [14]. In this present work, the effect of solution concentration on structural, morphological and optical properties of ZnO thin films prepared by spray pyrolysis method at pre-optimized substrate temperature have been studied.…”

“…3. This is because with increasing the precursor concentration films are thicker and consequently less transparent [20] but especially roughness that promotes internal scattering leading to less transparent layers [21] and also the arrangement of atoms along different planes such as (1 0 1), (1 0 2) which leads to dispersion of light and diminish in transmittance in the visible range [14]. The observed interference effect in the T and R spectra are an evidence for mirror like reflecting films.…”

Microstructure, characterizations, functionality and compressive strength of cement-based materials using zinc oxide nanoparticles as an additive

“…ZnO has been known as a representative of the photocatalyst among semiconductors which has a direct band gap (3.3 eV at room temperature), due to their high photocatalytic activity, photocatalytic degradation of organic compounds and strongly resist microorganisms [19][20][21]. It is widely used as an additive into numerous materials and products including plastics, ceramics, paints and glass.…”

Direct sunlight responsive Ag–ZnO heterostructure photocatalyst: Enhanced degradation of rhodamine B

“…The lattice fringe with interplanar spacing of 0.221 nm was corresponding to the (101) plane of ZnO. This close interconnection between Ag cores and ZnO shells was believed to favor the transfer and separation of photo-generated electrons from ZnO shells to the silver cores [32][33][34], which in turn affected its photocatalytic activity.…”
