More Information
Summary:A luminescent diamond is made by subjecting a volume of diamond grains to high-pressure/ high-temperature conditions with or without a catalyst to cause the grains to undergo plastic deformation to produce nitrogen vacancy defects in the diamond grains, increasing the luminescent activity/intensity of the resulting diamond material. The consolidated diamond material may be further treated to further increase luminescent activity/intensity, which treatment may comprise reducing the consolidated diamond material to diamond particles, heat treatment in vacuum, and air heat treatment, which reducing process further increases luminescent activity/intensity. The resulting luminescent diamond particles display a level of luminescence intensity greater than that of conventional luminescent nanodiamond, and may be functionalized for use in biological applications. 发光金刚石是这样制成的：通过使一定体积的金刚石晶粒在有或无催化剂的情况下经受高压/高温条件以使晶粒经历塑性变形，以在金刚石晶粒中产生氮空位缺陷，从而提高产生的金刚石材料的发光活性/强度。可进一步处理固结的金刚石材料以进一步增加发光活性/强度，该处理可包括将固结的金刚石材料减小为金刚石颗粒、真空热处理和空气热处理
