title: Local temperature variation measurement by anti-Stokes luminescence in attenuated total reflection geometry.
abstract: Strong temperature dependence of anti-Stokes luminescence intensity from Rhodamine 101 is used to probe local temperature variation at a surface region in the attenuated total reflection geometry (ATR), when heating with laser light. In this method, the measured region can be limited by observing evanescent luminescence. The near-field depth (penetration depth) was changed by the observation angle θoutof the evanescent luminescence and the spatial temperature variation was observed.
