Fig. 8From: Influence of Atomic Hydrogen, Band Bending, and Defects in the Top Few Nanometers of Hydrothermally Prepared Zinc Oxide NanorodsRoom temperature photoluminescence spectra of the ZnO NRs before and after H* treatment. a PL for sample without H2O. b Energy position of defects in sample without H2O. c PL for sample with H2O. d Energy position of defects in the sample with H2O. The relative of the green emission intensity peak at 2.35 eV with respect to the UV emission is denoted as R valueBack to article page
