    • Provided is a process of forming a Cd and Se containing nanocrystalline composite. The nanocrystalline composite has a composition of one of (a) Cd, M, Se, (b) Cd, Se, A, and (c) Cd, M, Se, A, with M being an element of group (12) of the PSE other than Cd and A being an element of group (16) of the PSE other than O and Se. In one embodiment in a suitable solvent a solution of the element Cd, or a precursor thereof, and, where applicable, of M, or a precursor thereof is formed. To the solution the element Se and, where applicable, A is added and thereby a reaction mixture formed. The reaction mixture is heated for a sufficient period of time at a temperature suitable for forming the Cd and Se containing nanocrystalline composite and then the reaction mixture is allowed to cool. Finally the Cd and Se containing nanocrystalline composite isolated. In another embodiment the reaction mixture is formed by adding into a suitable solvent the element Cd, or a precursor thereof, Se, where applicable M and where applicable A. In this embodiment the reaction mixture is heated and water formed during the process is being removed.
    • 提供了形成含Cd和Se的纳米晶复合材料的方法。 纳米晶复合物具有(a)Cd,M,Se,(b)Cd,Se,A和(c)Cd,M,Se,A中的一种的组成,M是组(12)的元素 除了Cd和A之外的PSE是除了O和Se之外的PSE的组(16)的元素。 在一个实施方案中,在合适的溶剂中,形成元素Cd或其前体,以及适用的M或其前体的溶液。 向溶液中加入元素Se和(如适用)A,形成反应混合物。 将反应混合物在适于形成含Cd和Se的纳米晶复合材料的温度下加热足够的时间,然后使反应混合物冷却。 最后分离Cd和Se纳米晶复合物。 在另一个实施方案中,反应混合物通过在合适的溶剂中加入元素Cd或其前体Se,在适用的情况下,在适用的情况下加入A.在该实施方案中,反应混合物被加热并且在该过程中形成的水​​被除去 。
