Synthesis of ordered nanorod arrays
| DWPI Title: Synthesizing ordered nanorod arrays involves providing colloidal suspension of nanorods having hydrophobic surface in non-polar solvent, and counter-diffusing non-polar solvent and polar anti-solvent into each other to form solvent/anti-solvent mixture, for precipitating ordered nanorod arrays |
| Abstract: A bi-phased approach between good solvents (or non-polar) and bad solvents (polar) can be used to assemble nanorods into highly ordered monolayers or multilayers of ordered nanorod arrays. These ordered nanorod arrays can display unique optical properties. For example, ordered arrays of CdSe/CdS core/shell nanorods were assembled that display polarized photoluminescence. |
| Use: Method for synthesizing ordered nanorod arrays. |
| Advantage: The method enables to assemble nanorods into highly ordered monolayers or multilayers of ordered nanorod arrays. The ordered nanorod arrays can display unique optical properties. |
| Novelty: Synthesizing ordered nanorod arrays involves providing a colloidal suspension of nanorods having a hydrophobic surface in a non-polar solvent, and counter-diffusing the non-polar solvent and a polar anti-solvent into each other to form a solvent/anti-solvent mixture, for slowly precipitating ordered nanorod arrays from the colloidal suspension. |
