The systematic test and analysis of the spectral characteristics and color mechanism of the synthetic jadeite are carried out by using electron probe,X-ray powder diffraction,Fourier transform infrared spectroscopy,laser Raman spectra and UV-VIS absorption spectra and photoluminescence spectra.The research results show that the appearance,mineral composition,Raman spectra,and photoluminescence spectra of the synthetic jadeite are almost the same as natural jade.However,there are obvious differences between FTIR,UV-VIS and chemical components.The specific performance is as follows:the low content of Fe leads to the loss of 437 nm absorption band in the visible range; in addition,the differences of content of trace elements and formation environment lead to large differences of infrared absorption band caused by stretching vibration of ν(M/Cr-O) and ν as (M-OH). ? 2018, Editorial Board of Chinese Journal of High Pressure Physics.
