Synthesis of silane surface modified ZnO quantum dots with ultrastable, strong and tunable luminescence.

Surface modified ZnO quantum dots (QDs) with ultrastable, strong and tunable luminescence have been successfully prepared via silanization during the growth process by (3-(2,3-epoxypropoxy)propyl)trimethoxysilane. The as-prepared ZnO QDs are demonstrated to be promising for anti-counterfeit applications in expensive high-end liquors, etc. This journal is © The Royal Society of Chemistry 2011
