    • Methods of forming a nanocrystal are provided. The nanocrystal may be a binary nanocrystal of general formula M1A or of general formula M1O, a ternary nanocrystal of general formula M1M2A, of general formula M1AB or of general formula M1M2O or a quaternary nanocrystal of general formula M1M2AB. M1 is a metal of Groups II-IV, Group VII or Group VIII of the PSE. A is an element of Group VI or Group V of the PSE. O is oxygen. A homogenous reaction mixture in a non-polar solvent of low boiling point is formed, that includes a metal precursor containing the metal M1 and, where applicable M2. For an oxygen containing nanocrystal the metal precursor contains an oxygen donor. Where applicable, A is also included in the homogenous reaction mixture. The homogenous reaction mixture is under elevated pressure brought to an elevated temperature that is suitable for forming a nanocrystal.
    • 提供了形成纳米晶体的方法。 纳米晶体可以是通式M1A或通式M1O的二元纳米晶体,通式M1M2A的三元纳米晶体,通式M1AB或通式M1M2O或通式M1M2AB的季纳米晶体。 M1是PSE的II-IV族,VII族或VIII族的金属。 A是PSE的第VI组或第V组的要素。 O是氧气。 在低沸点的非极性溶剂中形成均匀的反应混合物,其包括含有金属M1的金属前体,以及适用的M2。 对于含氧纳米晶体,金属前体含有氧供体。 在适用的情况下,A也包含在均匀的反应混合物中。 均匀的反应混合物在升高的压力下达到适于形成纳米晶体的升高的温度。
