AI Technical Summary
Existing mineral luminescence analysis methods cannot accurately characterize the luminescence properties of blue calcite, and it is difficult to effectively distinguish and quantify the contributions of different luminescence centers, resulting in low sensitivity and poor accuracy, which cannot meet the high-precision analysis needs of scientific research and application fields.
By combining multi-wavelength excitation with time-resolved spectral analysis, along with luminescence center identification algorithms and spectral deconvolution analysis techniques, and through various excitation wavelengths and temperature gradient tests, we can identify and distinguish manganese ions, rare earth ions, and lattice defect luminescence centers in blue calcite, and establish a quantitative relationship between luminescence intensity and content.
It achieves comprehensive characterization and high-precision quantitative analysis of the luminescence properties of blue calcite, with an identification accuracy of 98%, a quantitative detection sensitivity improved by 2-3 orders of magnitude, and a quantitative accuracy of over 95%, providing comprehensive and reliable support for mineral identification and gemological applications.
