文摘
- •
In2O3 samples with various nanocrystals size are prepared by sol–gel method.
- •
The mean nanocrystals size varies from 7 to 8 nm to 39–41 nm.
- •
Optical band gap of the nanocrystalline In2O3 samples is equal to 2.8 eV.
- •
We propose the model clearing up the phenomenon of persistent photoconductivity in In2O3.
- •
Slow photoconductivity decay in In2O3 is fitted by a stretched-exponential function.
