摘要：

Highly stable, wurtzite quantum sized ZnO colloids encapsulated in polymers have been synthesized. The particles can be obtained in a powder form and are partially redissolvable in organic media. A shift in the optical absorption spectrum confirms quantum size effects. Stationary fluorescence measurements exhibit excitonic as well as trapped fluorescence. The intensity of trapped fluorescence changes with capping. The time resolved fluorescence measurements indicate considerably short decay times.
