چکیده
Abstract An experimental detail on the morphology engineering and characterizations of all-inorganic Sn-based perovskite (here CsSnI 3 ) thin films their application in photodetectors are presented. In particular, we demonstrated that chlorobenzene anti-solvent treatment during thin-film spin coating could effectively optimize properties obtained film. SEM AFM measurements showed uniform film with nanorod-like nanocrystalline morphology. addition, EDS XPS confirmed low level oxidation film, indicating good ambient stability. A planar photodetector was also made prepared electrical characteristics were taken. The dark current photocurrent found range 10 −9 −7 A, respectively, an on/off ratio 2 . photoresponsivity −5 AW −1 further experiment conducted to make composite between CNTs for additional morphological engineering. measurement Raman mapping manifested nanonet-like quenching photoluminescence curve indicated efficient photo-generated carrier extraction from matrix CNTs. absorption spectra enhanced ability hybrid −6 −4 −2 Due combination , increased 1000 times. At same time, hysteresis reduced significantly compared pristine -based photodetector.

A self-powered UV photodetector based on TiO2 nanorod arrays
Large-area vertical rutile TiO2 nanorod arrays (TNAs) were grown on F/SnO2 conductive glass using a hydrothermal method at low temperature. A self-powered ultraviolet (UV) photodetector based on TiO2 nanorod/water solid-liquid heterojunction is designed and fabricated. These nanorods offer an enlarged TiO2/water contact area and a direct pathway for electron transport simultaneously. By connect...

Carbon nanotubes are attractive approach for designing of new membranes for advanced molecular separation because of their unique transport properties and ability to mimic biological protein channels. In this work the synthetic approach for fabrication of carbon nanotubes (CNTs) composite membranes is presented. The method is based on growth of multi walled carbon nanotubes (MWCNT) using chemic...
متن کاملHybrid nanorod-polymer solar cells.
We demonstrate that semiconductor nanorods can be used to fabricate readily processed and efficient hybrid solar cells together with polymers. By controlling nanorod length, we can change the distance on which electrons are transported directly through the thin film device. Tuning the band gap by altering the nanorod radius enabled us to optimize the overlap between the absorption spectrum of t...
