Low-Temperature Fabrication of Light-Emitting Zinc Oxide Micropatterns Using Self-Assembled Monolayers

ZnO micropatterning under very mild conditions is presented. Photolysis (using a mask) of Si–C bonds in a self-assembled phenylsilane layer yields a patterned phenyl/hydroxy surface. ZnO is selectively deposited at 55 °C on the phenyl domains by electroless deposition using a Pd catalyst adhered to the surface. The viability of the ZnO pattern as a phosphor is illustrated by the visible light cathodoluminescence image shown in the Figure and on the cover.
