Luminescent semiconductor nanomaterials, such as metalselenide (CdSe, ZnSe, PbSe), have been of great interest because of their unique quantization phenomena1 and potential applications in optoelectronic devices and biology. And, block copolymer, which forms micellar structures in a selective solvent, provides an excellent platform for realizing highly ordered 2-D nanoparticle arrays with easy control of size and interparticle spacing. Here, we report the direct and simple preparation of CdSe nanoparticles in polystyrene-block-poly(4-vinylpyridine) copolymer micelle core and 2-D array fabrication with variable heights on the solid substrate. The height of the CdSe nanoparticles was varied by changing the concentration of metal salt in the micelle solution. Optical investigation of the CdSe nanoparticles in micelle solution demonstrates the bulk as well as quantized phenomena. |
