Description
<p>Diamond emits characteristic fluorescence due to optical defects and impurities. Inspection using fluorescence is a very important item in gem identification, such as a method of visually observing fluorescence to ultraviolet light, fluorescence image analysis with DiamondViewTM, and measurement with an optical instrument. A natural pink diamond and a synthetic pink diamond show distinctive fluorescence. The wavelength distribution of the fluorescence was measured with a fluorescence spectrofluorometer. The excitation wavelength having the maximum fluorescence spectrum and the change in the fluorescence spectrum due to the fluctuation of the excitation wavelength was observed by measuring the 3D fluorescence spectrum.</p>
