Dual wavelength (ultraviolet and green) photodetectors using solution processed zinc oxide nanoparticles. ACS Applied Materials & Interfaces, 9(42), 36971-36979. https://doi.org/10.1021/acsami.7b08092

Narrow-band photoconductivity with a spectral width of 0.16 eV is obtained from solution-processed colloidal ZnO nanocrystals beneath the band-edge at 2.25 eV. A new model involving electron transfer from deep defects to discrete shallow donors is in...
