Document Type and Number:
WIPO Patent Application WO/2022/186283
Kind Code:
A1
Abstract:
The present invention makes it possible to reduce the device size and manufacturing cost. This temperature detection device 1 comprises: a sensor unit 22 having a light-emitting-substance-added semiconductor 23, a pair of electrodes 25, 26 provided on the surface of the light-emitting-substance-added semiconductor 23, and a light-emitting substance 24 disposed at a prescribed position in the light-emitting-substance-added semiconductor 23, the light-emitting substance 24 emitting light due to a current flowing through the light-emitting-substance-added semiconductor 23, the light emission spectrum of the light-emitting substance 24 changing according to the temperature; a voltage application unit 21 for applying a prescribed voltage between the pair of electrodes 25, 26; a light detection unit 31 for detecting light from the light-emitting substance 24; and a control unit 32 functioning as a temperature detection unit for detecting the temperature at the position at which the light-emitting substance 24 is installed, according to the light from the light-emitting substance 24.
