    Abstract: A spectroscopic measurement apparatus includes a light source, an integrator, a spectroscopic detector, and an analysis unit. The integrator includes an internal space in which a measurement object is disposed, a light input portion for inputting light to the internal space, a light output portion for outputting light from the internal space, a sample attachment portion for attaching the measurement object, and a filter attachment portion for attaching a filter unit. The filter unit has a transmission spectrum in which an attenuation rate for excitation light is larger than an attenuation rate for up-conversion light, and attenuates the light output from the light output portion. The analysis unit analyzes luminous efficiency of the measurement object on the basis of the transmission spectrum data and the spectroscopic spectrum data acquired by the spectroscopic detector.

    Abstract: A spectrometry device includes a light source, an integrator configured to have an internal space in which a long afterglow emission material is disposed and output detection light from the internal space, a spectroscopic detector, an analysis unit configured to analyze a photoluminescence quantum yield of the long afterglow emission material, and a control unit configured to control switching between presence and absence of input of excitation light to the internal space and an exposure time in the spectroscopic detector. The control unit controls the light source so that the input of the excitation light to the internal space is maintained in a first period and the input of the excitation light to the internal space is stopped in a second period, and controls the spectroscopic detector so that an exposure time in the second period becomes longer than an exposure time in the first period.
