The present invention provides substantially monodisperse colloidal nanocrystals and new preparative methods for the synthesis of substantially monodisperse colloidal nanocrystals. These synthetic methods afford the ability to tune nanocrystal size and size distribution. By using non- coordinating solvents in the synthetic process, these procedures constitute easier, less expensive, safer, and more environmentally "green" methods than those currently in use. This invention is generally applicable to any II-VI or III-V semiconductor material, and may be useful in generating metal-nonmetal compounds involving transition metals as well.
La présente invention porte sur des nanocristaux colloïdaux pratiquement monodispersés et sur de nouveaux procédés de préparation pour leur synthèse. Ces procédés synthétiques ont la capacité d'accorder la taille et la granulométrie des nanocristaux. En utilisant des solvants sans coordination dans le processus de synthèse, ces procédures constituent des procédés plus faciles, moins chers, plus sûrs et plus écologiques que ceux couramment utilisés. Cette invention peut être appliquée à n'importe quel matériau semi-conducteur des groupes II-VI ou III-V, et peut être utile pour générer des composés métalliques-non métalliques mettant également en oeuvre des métaux de transition.
