Description

technical field

[0001] The invention belongs to the technical field of preparation of rare-earth doped luminescent materials, and in particular relates to a Yb 3+ , Tm 3+ / Ho 3+ Co-doping K 3 Y(PO 4 ) 2 Upconversion luminescent material and preparation method thereof.

[0002] technical background

[0003] In science, industry, military and many other fields, temperature is one of the most important parameters, and its accurate measurement and calibration is the key research work in this technical field. Traditional temperature detection sensors are based on the principle of thermal expansion and contraction of liquids or metals, but they generally must be in contact with the body of the material to be measured, and cannot achieve submicron or even nanoscale temperature measurement, temperature detection of cells in living organisms, and corrosive environments. Temperature measurement; in order to solve this technical problem, those skilled in the art have proposed a no...
