Surface temperatures, which are important in many combustion and energy transfer
processes, can be measured optically using rare-earth or transition metal doped ceramic …

The temperature-dependent characteristics of fluorescence of several rare-earth-doped
ceramic phosphors has made these materials the focus of a major effort in the field of …

Thermographic phosphor thermometry enables surface temperatures to be measured over a
wide range extending from sub 0° C to in excess of 1400° C by utilising the temperature …

The possibility of optical heating with simultaneous control of the generated light within a
single phosphor is particularly attractive from the perspective of multiple applications. This …

An algorithm for the non-ambiguous reduction of multi-exponentially decaying luminescence
signals to scalar lifetimes is described and characterised. Whereas this investigation stems …

In the present study, the influence of gas compositional and pressure conditions on
thermographic phosphor thermometry was investigated. A heatable pressurized and optical …

Luminescence thermometers exhibiting ratiometric response in their emission spectrum are
widely investigated but to obtain two‐dimensional measurements, either the emission …

The paper describes the application of thermographic phosphors for surface temperature
measurements in gas turbine combustors and on surrounding components. Thermographic …

Apart from the temperature, four parameters were investigated for their impact on the
phosphorescence characteristics of Mg 4 FGeO 6: Mn with regards to phosphor …

In this study a novel technique for 2D spray temperature measurement is presented. For this
purpose the thermographic phosphor (TP) Mg 4 GeO 5.5 F: Mn was dispersed in n …
