TEMPERATURE MEASURING DEVICE, AND TEMPERATURE MEASURING METHOD
Document Type and Number:
WIPO Patent Application WO/2022/244716
Kind Code:
A1
Abstract:
[Problem] To provide a temperature measuring device capable of measuring a cell temperature in a living body. [Solution] This temperature measuring device consists of a quantum dot 1, a light emitting unit 2, a light detecting unit 3, a light intensity ratio calculating unit 4, a calibration curve storage unit 5, and a temperature calculating unit 6. The quantum dot 1 has a core-shell type structure. A core 10 of the quantum dot 1 has crystal defects. The light emitting unit 2 is a device for emitting exciting light onto the quantum dot 1. The light detecting unit 3 is a device for measuring a light intensity I1 at a peak wavelength of band edge emission, and a light intensity I2 at a peak wavelength of defect emission. The light intensity ratio calculating unit 4 is a device for calculating a light intensity ratio I2/I1. The calibration curve storage unit 5 is a device for storing a calibration curve representing a correspondence between the light intensity ratio I2/I1 and a temperature at the periphery of the quantum dot 1. The temperature calculating unit 6 is a device for calculating the temperature at the periphery of the quantum dot 1 from the light intensity ratio I2/I1 and the calibration curve.
