Abstract: A method for regulating a photoelectric spectral response range, including: pre-pressurizing a gasket material, and drilling a circular hole at the center of indentation as a sample chamber; padding the sample chamber with a layer of photoelectric material, where two ends of the photoelectric material each are connected to one platinum sheet as an electrode; respectively connecting the two electrodes to probes of a digital source-meter, and using the digital source-meter to apply a 5 V bias voltage to the photoelectric material; placing a pressure calibration substance for pressure calibration; applying a high pressure to the photoelectric material, to make a pressure in the sample chamber reach a preset pressure; irradiating a near-infrared laser onto the photoelectric material through diamonds, controlling the presence or absence of illumination, and using the digital source-meter to display a current-time curve at the preset pressure; and determining a photoelectric spectral response range.
