A hydrated basic sulfate precursor for In2O3 is facilely prepared from the mixed indium nitrate and ammonium sulfate solutions via means of single‐step hydrolysis precipitation at a relatively low synthetic temperature of ≈60 °C, which subsequently converts to an oxide powder via pyrolyzing. The morphologies of the precursor and oxide can be controlled via adjusting volume fractions of ethanol‐water...
We carried out a nitrogen plasma treatment process to obtain N‐doped ZnO single crystal. The treated sample showed an acceptor related emission located at 3.354 eV when excited by a 325‐nm He–Cd laser at 85 K. Raman spectra revealed the formation of a bond between Zn and N atoms. The surface work function indicated increasing of hole concentration of the N‐plasma‐treated ZnO. By constructing a ZnO‐based...
