摘要：

We present a novel method to produce a PMMA-quantum-dot (QD) composite fabricated by pre-polymerization of PMMA and dispersing commercially available colloidal semiconductor QDs. The QDs are stabilized in rapidly formed oligomer matrices, and the complete polymerization of the PMMA-QD composite is achieved by commonly used polymerization. The properties of the PMMA-QD composite are measured and compared with the QDs in colloidal solution. Patterning of the PMMA-QD composite by direct write electron beam shows its promising applications in optoelectronics. (C) 2005 Optical Society of America.
