OPTICAL PROPERTIES OF ZnO COMPOSITE NANOPARTICLES

doi:10.1088/1004-423X/7/3/007

Abstract

Abstract We have synthesized core/shell structure ZnO composite nanoparticles by surface chemical modification. This new composite material shows a large optical gap redshift compared with the homogeneous ZnO nanoparticles. The visible photoluminescence ranging from blue to red in color with fast decay time may be as signed to the interfacial bound-exciton-like emission.
