UV narrow-band photodetector based on indium oxide nanocrystals

(Lobachevsky University) An international team of researchers from Russia and India has created a narrow-band UV photodetector based on indium oxide nanocrystals embedded in a thin film of aluminum oxide.Semiconductor quantum dots (nanocrystals just a few nanometers in size) have attracted researchers' attention due to the size dependent effects that determine their novel electrical and optical properties. By changing the size of such objects, it is possible to adjust the wavelength of the emission they absorb, thus implementing selective photodetectors, including those for UV radiation.
