“…Thin films of doped and undoped ZnO are used in photovoltaics as transparent conducting oxides (TCOs) and buffer layers [2,7,8]. Boron (B)-doping offers a more sustainable alternative to indium tin oxide (ITO), a rare-earth element, in TCO materials [9,10].…”

Investigations have been conducted into the structure, morphology, thickness, and optical properties of ZnO thin film upon doping it with Boron from boric acid (H3BO3) at a constant concentration and annealing it at various temperatures (200, 300, and 400 °C). The thin films were formed on glass substrates using the spray pyrolysis process at 250°C, and they were then annealed for two hours in air at various temperatures. It was discovered that the annealing temperature and boron doping had a substantial impact on all properties of the ZnO nanostructure. The polycrystalline hexagonal wurtzite structure is present in both ZnO and BZO thin films. With high optical transmission (≥70%), crystallite diameters of 25.8 to 28.5 nm for ZnO and 15.96 to 24.80 nm for BZO, respectively, and significant absorbance up to 400 nm at the maximum annealing temperature (400 °C) for both films. Moreover, the as-deposited and annealed BZO films had optical band gaps of 3.04 eV and 2.9 eV, respectively, which are less than the ZnO film's 3.23 eV band gap; in general, as the annealing temperature increased it decreased.

“…[ 5,6 ] As a result, there is a growing interest in developing PDs specially designed for UV‐C detection. To mitigate interference from solar radiation, [ 7,8 ] such detectors primarily rely on wide bandgap semiconductors such as SiC, [ 9 ] GaN, [ 10–14 ] a‐MoSx‐decorated p ‐AlGaN/n‐GaN nanowires, [ 15 ] NdNb 2 O 7 , [ 16 ] MoO 3 , [ 17 ] TiO 2 , [ 18 ] etc. Wide bandgap semiconductors such as TiO 2 , [ 18 ] ZnO, [ 19 ] and SnO 2 [ 20 ] are emerging as promising and cost‐effective materials for UV‐C detection in recent research.…”

This study demonstrates the development of an ultraviolet‐C photodetector fabricated using a surface‐passivated SnO2 thin film deposited via spray pyrolysis. This photodetector possesses an unprecedentedly fast response speed, with both rise time and decay time of 0.3 milliseconds. Furthermore, even when subjected to a modest UV light intensity of 6 μW/cm2, the device shows a significantly high responsivity of 1500 A/W, external quantum efficiency of 7 × 105 %, and detectivity of 1013 Jones. When compared to previously reported SnO2‐based photodetectors, this device exhibits consistent performance over a long working time, which may be due to the suppression of surface vacancy defects via surface passivation, as observed from structural and optical measurements. This type of photodetectors has the potential to be useful in wide range of applications, including industrial sensing, medical diagnostics, and environmental monitoring.This article is protected by copyright.
