The present invention is directed to methods of preparing metal sulfide, metal selenide, or metal sulfide/selenide nanoparticles and the products derived therefrom. In various embodiments, the nanoparticles are derived from the reaction between precursor metal salts and certain sulfur- and/or selenium-containing precursors each independently having a structure of Formula (I), (II), or (III), or an isomer, salt, or tautomer thereof, where Q1, Q2, Q3, R1, R2, R3, R5, and X are defined within the specification.
本发明涉及制备金属硫化物、金属硒化物或金属硫化物/硒化物纳米颗粒及其衍生产品的方法。在不同的实施方案中,纳米颗粒由前体金属盐和某些含硫和/或硒的前体反应得到,这些前体各自独立地具有式 (I)、(II) 或 (III) 结构,或其异构体、盐或同系物,其中 Q1、Q2、Q3、R1、R2、R3、R5 和 X 在说明书中定义。
