Abstract
A luminescent temperature sensor comprising (i) an object having a recess, (ii) a layer of luminescent material disposed in the recess, wherein the luminescent material emits electromagnetic radiation having a detectable optical characteristic that is functionally dependent on the temperature of the object, and (iii) a light waveguide in optical communication with the layer of luminescent material, is provided. A test device for measuring a temperature in a processing step comprising (i) an object having a surface and having a recess in the surface of the object, (ii) a layer of luminescent material disposed in the recess, wherein the luminescent material emits electromagnetic radiation having a detectable optical characteristic that is functionally dependent on the temperature of the object in response to a source of excitation radiation, and (iii) an optical window that seals said layer of luminescent material in the recess in the surface of the object, is provided.
