Jul 20, 2018 · We report a new method as UV treatment of low-temperature processed to obtain tin oxide (SnO2) electron transport layers (ETLs). The results show that the high quality of ETLs can be produced by controlling the thickness of the film while it is treated by UV.

These low temperature solution-processed and UV-sintered SnO 2 films are suitable for the low-cost, large yield solution process on a flexible substrate for optoelectronic devices.

SnO2: Ag/P–Si photodetectors demonstration the highest described visible responsivity of (0.287 A/W) with the Ag ratio of (0.03). I–V characteristics with different power density were measured.

May 27, 2024 · Self-powered heterojunction PDs having ultraviolet–visible–near-infrared broadband photoresponse were constructed by using SnO 2 nanopillars and CuInS 2 nanoflakes. The dimension, crystalline quality, and energy level structure of the SnO 2 nanopillars were regulated by changing the concentration of Sn ions in the precursor solution.

Dec 4, 2023 · In this work, a WSe 2 /SnO 2 heterostructure is prepared by hydrothermal synthesis. The attachment of SnO 2 to flower-like WSe 2 nanosheets can generate gas transmission and n–n heterojunction, resulting in improved sensitivity and decreased response/recovery time.

Mar 20, 2024 · Herein, we propose a room-temperature-processed tin oxide (SnO 2) ETL preparation method for flexible PQD solar cells. The process involves synthesizing highly crystalline SnO 2 nanocrystals...

Feb 1, 2024 · Using first-order kinetics, 100 °C ultraviolet (UV) annealed Cu 2 O–SnO 2 p-n heterojunction shows the superb fast degradation rate constant of 0.21 and 0.16 min −1 for methylene blue (MB) and methyl orange (MO) organic dyes, respectively, as photogenerated electron-hole pairs is increased.

The UV light-activated sensor fabricated from Au/SnO2 nanorods was found to exhibit excellent sensing properties for NO2 at room temperature, including a high response of 10 (at a concentration of 1 ppm), a theoretical detection limit of 21 ppt, and a fast response/recovery time of 1/5 s (${T}_{{60}}$ ) and 22/38 s (${T}_{{90}}$ ). In addition ...

Herein, the SnO 2 nanosheet array (NSA) photoanodes are fabricated and their good self-powered UV detection capability is demonstrated. The 3D structure of SnO 2 NSA not only improves the interfacial charge transfer and carrier transport but also enhances UV absorption.

Aug 1, 2022 · The 2D/0D hetero-interface, which improves the charge transport under UV light has led to enhanced optoelectronic property and UV-activated NO 2 sensing performance. A promising method for the fabrication of room-temperature TMDs-based gas sensors with high performance has been shown in this study.
