摘要： The analysis apparatus 10 includes a plasma generation device 11 and an optical analysis device 13. The plasma generation device 11 generates initial plasma by energizing a substance in space to be turned into a plasma state, and maintains the plasma state by irradiating the initial plasma with electromagnetic wave for a predetermined period of time. Then, the optical analysis device 13 analyzes the target substance 15 based on a time integral value of intensity of emission from the target substance 15 in an electromagnetic wave plasma region, which is maintained by the electromagnetic wave.

摘要： 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.
