A method of making crystalline inorganic particles having an average size of up to about 200 nm is disclosed. The crystalline inorganic particles include at least one crystalline inorganic chalcogenide and combinations thereof. Each crystalline inorganic particle includes at least one crystallite. The method includes the steps of: providing an organometallic precursor, wherein the organometallic precursor includes at least one of a metal alkoxide, a metal carboxylate, and combinations thereof; decomposing the organometallic precursor at a first temperature for a sufficient time to form an inorganic amorphous material; and crystallizing the inorganic amorphous material at a second temperature for a sufficient time to form a crystalline phase. Also disclosed are crystalline inorganic particles made by the method.
本发明公开了一种制造平均尺寸最大约为 200 纳米的结晶无机颗粒的方法。结晶无机颗粒包括至少一种结晶无机瑀及其组合。每个结晶无机颗粒包括至少一个晶粒。该方法包括以下步骤:提供有机金属前驱体,其中有机金属前驱体包括金属烷氧基、金属羧酸盐及其组合中的至少一种;在第一温度下分解有机金属前驱体足够长的时间以形成无机无定形材料;以及在第二温度下结晶无机无定形材料足够长的时间以形成结晶相。还公开了用该方法制造的结晶无机颗粒。
