Patent number: 8614452Abstract: The light extraction efficiency of a typical light-emitting diode (LED) is improved by incorporating one-dimensional ZnO nanorods. The light extraction efficiency is improved about 31% due to the waveguide effect of ZnO sub-microrods, compared to an LED without the nanorods. Other shapes of ZnO microrods and nanorods are produced using a simple non-catalytic wet chemical growth method at a low temperature on an indium-tin-oxide (ITO) top contact layer with no seed layer. The crystal morphology of a needle-like or flat top hexagonal structure and the density and size of ZnO microrods and nanorods are easily modified by controlling the pH value and growth time. The waveguide phenomenon in each ZnO rod is observed using confocal scanning electroluminescence microscopy (CSEM) and micro-electroluminescence spectra (MES).Type: GrantFiled: April 26, 2011Date of Patent: December 24, 2013Assignee: Gwangju Institute of Science and TechnologyInventors: Ki-Seok Kim, Gun-Young Jung, Sang-Mook Kim, Mun-Seok Jeong, Hyun Jeong
