The invention is directed to a microscopic method for measuring a spatio-temporal temperature profile of an object. The microscopic method of the invention comprises: i) providing a coating onto said object, wherein the coating comprises at least one luminophore having a temperature dependent luminescence quantum yield and is in thermal contact with the surface of said object; iii) performing the sequence of a) subjecting at least part of the coated object to heat, wherein said heat defines a time, t0; b) waiting for a delay period p; c) subjecting at least part of the coated object to a photoexcitation pulse at a time, t1, after t0, thereby photoexciting at least part of the luminophores, wherein t1 = t0 + p; d) collecting a luminescence image from the photoexcited luminophores during a time interval ?t, starting at a time t2, at or after t1; and e) optionally repeating steps a)-d) for a number of times to improve signal to noise ratio; iv) repeating step iii) for a number of times wherein in each step iii) a different delay period p is applied; and vi) converting the collected luminescence image at each delay period p to a temperature image using a pre-determined calibrated relation between luminescence intensity and temperature.
摘要:
Matriz orgánica-inorgánica luminiscente que contiene complejos tris (beta-dicetonato) de cationes de dos lantánidos diferentes, europio y terbio. Opcionalmente la matriz comprende nanopartículas magnéticas de óxido de hierro recubiertas. La matriz puede componerse de polímeros inorgánicos basados en siloxano derivatizados con grupos orgánicos (por ejemplo diureasilo, diuretanosilo o cualquier otro híbrido amino-funcionalizado). El procedimiento de obtención de la matriz comprende preparar disoluciones de complejos tris (beta-dicetonato) de cationes de lantánidos y polimerizar una mezcla de precursor de la matriz que contenga disoluciones de dichos complejos. Un termómetro molecular luminiscente comprende la matriz anterior, una fuente de excitación y un equipo de detección de la luminiscencia. La intensidad de la emisión del Eu(III) es independiente de la temperatura lo que permite un autocalibrado del termómetro al estimarse el grado de fotoblanqueado. La medida de la temperatura absoluta se realiza comparando la intensidad relativa entre las emisiones del Tb (III) y del Eu (III).
摘要:
Temperature probes for measuring the temperature of objects are disclosed. The temperature probes include a housing and a tip in thermal contact with an end of the housing. The tip is adapted to contact a surface of the object whose temperature is to be measured by the temperature probe. A portion of the housing in contact with the tip has a high thermal resistance effective to thermally isolate the tip from an adjacent portion of the housing. A sensor is located inside of the housing and adapted to measure the temperature of the tip.
