Abstract
Photoluminescence and visible light thermal radiation from Eu, Al doped SiO2 (SiO2:Eu, Al) glass fiber have been studied for a fiber-optic thermometer application. Photoluminescence (PL) peaking at λ=433, 485 and 617nm is clearly observed from SiO2:Eu, Al glass with UV excitation (λ=365nm). Peak intensity of PL decreases with temperature form 300 to 1000K. Visible light thermal radiation peaking at λ=660nm is also observed from SiO2:Eu, Al glass above 1000K. Peak intensity of visible light thermal radiation increases exponentially with temperature. Temperature can be measured based on temperature dependences of PL (below 1100K) and visible light thermal radiation (above 1000K) using SiO2:Eu, Al glass fiber. The hybridization of fluorescence thermometry (below 1000K) and thermal radiation thermometry (fiber-optic pyrometer, above 1000K) using SiO2:Eu, Al glass fiber is thought to extend the temperature range of a fiber-optic thermometer.
