  • Fluorescent temperature of the phosphor is dependent. Because of this dependency, the temperature of the thermal insulation layer with the phosphor is inferred. So that this connection can be established, the thermal insulation layer is optically accessible for the excitation light in the UV range. At the same time, it is ensured that the luminescent light from the phosphor can be emitted and detected by the thermal insulation layer.

Abstract

L'invention concerne un agencement d'au moins une couche d'isolation thermique (3) sur un corps de support (2), ladite couche servant à empêcher un transfert de chaleur entre le corps de support et une zone environnante (7) de ce dernier. Cette couche d'isolation thermique présente au moins une substance luminescente pouvant être excitée au moyen d'une lumière d'excitation, présentant une longueur d'onde d'excitation déterminée, pour émettre une lumière par luminescence, présentant une longueur d'onde d'émission déterminée. Au moins une autre couche d'isolation thermique (5), sensiblement dépourvue de substance luminescente, est présente. Cet agencement est caractérisé en ce que cette autre couche d'isolation thermique est sensiblement opaque à la lumière d'excitation servant à provoquer l'émission de lumière par luminescence et/ou à la lumière de la substance luminescente. Cette dernière contient au moins un oxyde mixte sélectionné dans le groupe de la pérovskite, de formule brute AA'03, et/ou du pyrochlore, de formule brute A2B207, A et A' représentant respectivement un métal trivalent et B un métal tétravalent. Cette couche d'isolation thermique s'utilise de préférence dans une turbine à gaz, l'état des couches d'isolation thermique pouvant être contrôlé de manière simple.
