Analyzing Method of Diamond Single Crystal Using Ultraviolet Photoluminescence

摘要

The present invention relates to a method for analyzing defects in diamond crystals using ultraviolet photoluminescence, according to the present invention, an ultraviolet irradiation step in which ultraviolet light emitted from a light source is irradiated to the surface side of a diamond single crystal; A photoluminescence image information acquisition step of acquiring photoluminescence image information by receiving a photoluminescence emitted from the surface side of the diamond single crystal irradiated with the ultraviolet light in the ultraviolet irradiation step and obtaining photoluminescence image information; And the photoluminescence image information acquired by the camera device in the photoluminescence image acquisition step is transferred from the camera device side to the data processing device side, and the diamond single crystal defects can be determined, so that the data processing is performed. A data processing step in which the device converts the photoluminescence image information into at least one color point that can be displayed on a predetermined color space; Since it contains, it is possible to analyze the defect distribution of diamond single crystal with high reliability.
