This invention pertains to surface-enhanced Raman scattering (SERS) detection technology, specifically disclosing a signal-squeezing SERS detection method for achieving quantitative analysis over an ultra-wide concentration range. It utilizes two-dimensional transition metal phosphorus-sulfur compounds with structural differences as the SERS substrate, modifying them through mechanical strain and chemical modification to enhance their sensitivity to specific and continuous concentration ranges. For each substrate, three parameters—characteristic peak intensity, signal-to-noise ratio (SNR), and detection probability—are extracted to construct a three-parameter calibration radar map for the corresponding concentration range.
