“…They observed that the average crystallite size of cubic In 2 O 3 gradually increased from 37 to 40 and 43 nm. In addition, Forsh et al [39] also showed that the size of In 2 O 3 NPs synthesised by sol–gel method increased from 8 to 20 nm when the calcination temperature was increased.…”

Indium oxide nanoparticles (In 2 O 3 NPs) were formed by calcining the optimised as-prepared indium hydroxide (In(OH) 3) NPs. The as-prepared In(OH) 3 NPs were synthesised at optimal pH 10 through co-precipitation method at various calcination temperatures (200, 300, 400, 500, 600°C) for 2 h. Characterisation of the samples was performed by thermogravimetric (TGA and differential thermal, DTA) analysis, high-resolution transmission electron microscope (HRTEM), X-ray diffractometer (XRD), Fourier transform infrared spectroscopy, and Raman spectroscopy. The complete conversion to In 2 O 3 NPs was reached at 300°C. Besides, the crystallite size of In 2 O 3 NPs calculated by William-Hall equation had the same trend with the values obtained from Scherrer equation. The HRTEM images also showed that the size of In 2 O 3 NPs was within the range of 15-28 nm. Clearly, their work confirmed that the smallest In 2 O 3 NPs (15 nm) with homogenous particle distribution were formed at a lower calcination temperature of 300°C.

Effect of cadmium-selenide quantum dots on the conductivity and photoconductivity of nanocrystalline indium oxide

The effect of cadmium-selenide quantum dots addition on the electrical and photoelectric properties of nanocrystalline indium oxide with nanocrystal dimensions in the range from 7 to 40 nm is studied. By impedance spectroscopy, it is shown that the addition of quantum dots substantially influences the resistance of interfaces between In 2 O 3 crystals. A change in the character of the photoconductivity spectrum of In 2 O 3 upon the addition of CdSe quantum dots is detected, and it is established that this change depends on the In 2 O 3 -nanocrystal dimensions. An energy band diagram is proposed to explain the observed change in the photoconductivity spectrum of In 2 O 3 upon the addition of CdSe quantum dots.

The influence of grain size on the sensitivity of indium oxide with extremely small grains in range of 7–40 nm to nitrogen dioxide in low concentration at room temperature is investigated under the UV illumination. It is found that the sample with the intermediate size of nanocrystals shows the greatest response to nitrogen dioxide. The possibility of using nanocrystalline In2O3 to create a sensor for detecting NO2 in air at room temperature under UV illumination is demonstrated. It is shown that pulsed illumination may be used for NO2 detection at room temperature that significantly reduces the sensor power consumption.
