Abstract
Contact thermometry and pyrometry have intrinsic limitations when it comes to probing temperature fields in hard-to-reach and extreme environments such as those encountered in energy systems (hot fluids, combustors, gas turbines, turbomachinery). Refractory thermosensitive phosphors, which show a well-defined temperature-dependent luminescence response, are functional materials with the potential to overcome these limitations.
In this talk I will present an overview of a series of high-temperature thermosensitive phosphors being studied in my research group. A common feature of these materials is their chemical and structural diversity, which makes them ideal platforms to exercise synthetic control over their temperature-dependent luminescence response. I will show how this response may be utilized to achieve luminescent thermometers capable of temperature sensing up to 1300 °C.
