    Abstract: In a detector for spectrometry attached to an integrating sphere, a plurality of detection elements having different spectral sensitivity characteristics is arranged side by side in the same plane on a base, and a side cover is provided such that the detection elements receive light. Thus, the measurement light is directly irradiated to the respective detection elements. Accordingly, the detector for spectrometry has a fast response speed and is excellent in the sensitivity characteristics in a wide wavelength region in the near-infrared area.

    Abstract: A spectroscopic measurement apparatus includes a light source, an integrator, a first spectroscopic detector, a second 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, and a sample attachment portion for attaching the measurement object. The first spectroscopic detector receives the light output from the integrator, disperses the light of a first wavelength region, and acquires first spectrum data. The second spectroscopic detector receives the light output from the integrator, disperses the light of a second wavelength region, and acquires second spectrum data. The first wavelength region and the second wavelength region include a wavelength region partially overlapping each other.

    Abstract: Photoluminescence quantum yield (PLQY) testing of quantum dots is described. In one embodiment, a method involves heating a sample including quantum dots and illuminating the sample with a light source. The method involves measuring spectra of luminescence from the illuminated quantum dots of the sample at each of a plurality of temperatures. The method involves measuring each of the plurality of temperatures with a temperature sensor. The PLQY at each of the plurality of temperatures is computed based on the measured spectra. The method further involves computing a relationship between QD emission wavelength of the measured spectra and the plurality of temperatures measured with the temperature sensor. The relationship is used to determine the QD temperature corresponding to each of the PLQY computations. In one embodiment, an integrating sphere moves on a gantry over the samples.
