Description
Technical Field
The invention relates to the technical field of temperature sensing, in particular to an optical temperature measuring method based on bismuth and manganese co-doped dual-luminescence characteristics, a high-sensitivity fluorescence temperature sensing material, a preparation method and application thereof.
Background
Temperature is a very important physical quantity, and its precise measurement is of great significance. With the rapid development of the internet of things technology, the characteristic requirements of the temperature sensor are increasing, for example, temperature monitoring in special environments such as strong electromagnetism, flammability and explosiveness. Conventional sensing devices using thermocouples or the like to monitor temperature using electrical signals have been unable to provide long-term stable temperature measurements. The development of optical temperature sensing technology is becoming more and more important.
At present, the optical temperature sensing technology mainly measures temperature through infrared temperature measurement and single rare earth luminescent ion thermal coupling energy level fluorescence intensity ratio. However, the infrared temperature measurement is affected by the interference environment, and the phenomena of large temperature measurement error and low sensitivity occur. For the rare earth ion thermal coupling energy level fluorescence intensity ratio temperature measurement technology, the energy level interval of the thermal coupling energy level must be between 200cm to meet the thermal coupling condition-1～2000cm-1In the meantime. However, the relative thermometric sensitivity is proportional to the energy level difference of the thermally coupled energy levels. Therefore, the thermal coupling condition limits the further improvement of the thermal coupling energy level fluorescence intensity of the single rare earth luminescent ion compared with the detection sensitivity and the signal detection discrimination of a temperature measurement scheme.
Therefore, it is very important to develop a new high-sensitivity temperature sensing method based on luminescent materials.
