Two-dimensional thermometry using temperature-induced line shifts of ZnO : Zn and ZnO : Ga fluorescence
Författare
Summary, in English
Sensitive temperature-induced line shifts of the near-band-edge emission from ZnO:Ga and ZnO:Zn are investigated for two-dimensional (2D) thermometry with nanosecond time resolution. Spectral and temporal concerns for 2D measurements and the feasibility for utilizing the line shifts for temperature measurements using a spectral ratio are investigated. Owing to the high temperature sensitivity, a precision of 1% at 800 K is reported for spectral ratio measurements. The technique is demonstrated by 21) measurements of the liquid temperature of burning methanol droplets. (C) 2008 Optical Society of America.
