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.

Abstract: A spectrometer 1A is provided with an integrating sphere 20 for observing measured light emitted from a sample S of a measurement target, and a Dewar vessel 50 which retains a medium R for regulating temperature of the sample S, so as to cover the sample S and a second container portion 50b of which is located so as to face the interior of the integrating sphere 20. The sample S can be easily regulated at a desired temperature with the use of the Dewar vessel 50 retaining the medium R so as to cover the sample S. As the second container portion 50b is located so as to face the interior of the integrating sphere 20, the temperature of the sample S is regulated by the medium R, while inhibiting an external ambience around the integrating sphere from affecting the sample S. Therefore, the sample S can be efficiently regulated at a desired temperature.
