Survivability of thermographic phosphors (YAG:Dy) in a combustion environment

Summary, in English

The feasibility of applying laser-induced phosphorescence in a combustion environment was shown by testing the consistency of the emission-temperature relations of thermographic phosphor particles (YAG:Dy). The relations were calibrated before and after the phosphor particles had passed a flame front. The calibrations were performed in air and in pure oxygen. The emission-temperature relation prevails from around 300 K to 1300 K. The difference in emission-temperature relation for the two different cases is less than the experimental precision (3%).
