| Abstract: | We investigate the properties of GaN semiconducting nanoparticles as a potential candidate for photodetection in the solar-blind
region. The photocurrent spectral response is studied spanning the range 1.6-5.5 eV. A significant fraction of the response
is in the range 4–5.5 eV. The results are compared to other optical properties and the origins of the features observed in
the spectra are speculated upon.
