測定装置。a first light source that emits excitation light to excite the sample; a second light source that emits calibration light with an intensity that cannot excite the sample and whose wavelength is known in advance; and light emitted from the first and second light sources. first and second chopper means for chopping light at different periods; first and twentieth twin amplifiers tuned to the respective chop periods of the first and second chopper means; a spectrometer;
The method includes a photomultiplier tube, irradiates the sample with light simultaneously emitted from the first and second light sources, and spectrally spectra the light excited by the irradiation and the light reflected by the sample using the spectrometer. A photoluminescence measurement characterized in that the spectral light is converted into an electric signal by the photomultiplier tube, and the intensity of each of the electric signals synchronized with the first and 20th twin amplifiers is outputted by each lock-in amplifier. Device.
