Scientists from Kazan Federal University (KFU) have developed an innovative method for measuring the temperature of microscopic objects using luminescent thermometry. The technology is based on the use of nanoparticles containing cerium (Ce³⁺) and terbium (Tb³⁺) ions, which allow for highly accurate temperature determination in the range of 0 to 200°C for objects a few micrometers in size.
The development is particularly important for microelectronics, where temperature control is critical for the stable operation of miniature devices. In addition, the method can be applied in the space industry and biomedicine, including biovisualization and photodynamic therapy.
Our work consists of studying the mechanisms of temperature sensitivity of the spectral-kinetic characteristics of these phosphors. It was shown that the obtained materials have very competitive sensitivity values.
The new method can significantly improve the control of temperature regimes in microchips, as well as increase the accuracy of medical procedures related to exposure to ionizing radiation.
