The PL-3000 Photoluminescence Spectrometer is based on the principle of photoluminescence. Since different types of diamonds exhibit different luminescence effects after being excited by laser, the instrument efficiently collects the luminescence spectra of diamonds after laser excitation for qualitative analysis. It is mainly used to identify small-particle type Ib yellow diamonds, natural type Ia diamonds, natural type IIa diamonds, as well as high-temperature high-pressure (HTHP) synthetic diamonds, CVD diamonds, etc. HTHP-treated type II diamonds show strong peaks at 575nm, 637nm, and 882nm, and CVD synthetic diamonds show strong peaks at 737nm; these are significantly different from natural diamonds. The instrument can collect diamond photoluminescence spectra under normal ambient conditions, making it a new type of analytical instrument for diamond identification. The instrument is highly integrated, has high sensitivity, and is easy to operate; a photoluminescence spectrum can be obtained in 1 second, providing a reliable basis for identification.
