A preparative route for a nanocrystalline CdSe/polymer nanocomposite that is easily integrated into photovoltaic device fabrication has been developed. Microwave assisted synthesis is used to initiate the reaction of relatively safe, inexpensive and air stable precursors. Particles size may be varied from 20 angstrom to 60 angstrom in diameter. The CdSe nanocrystals show near band-edge photoemission, are crystalline and may be incorporated into a poly( 9,9- dioctylfluorene- 2,7- diylalt-9- octylcarbazole- 3,6- diyl) copolymer. This polymer/CdSe composite can be directly cast, without complicated work-up, for the preparation of photovoltaic devices.
