Zusammenfassung:Thermally insulating ceramic layer system comprises an insulating layer (37) and a layer (39) containing a thermographic phosphor. This consists of YAG:Tm, YAG:EU, YSZ:Dy, GZO:Dy, GZO:Tm, YAG:Sm or EZO. Independent claims are included for: (A) turbine components with an insulating layer system as described; (B) use of EZO, YAG:Tm, YAG:EU, YSZ:Dy, GZO:Dy, GZO:Tm or YAG:Sm to produce phosphor layers in thermal insulation systems; and (C) apparatus for measuring the temperature of turbine component coated with the layer system comprising a solid state laser whose light is conducted by an optical fiber guide to the components, the light emitted by the phosphor layer being detected by a photomultiplier or camera and the laser beam positioned on the component using a mirror. Es wird eine Keramische Wärmedämmbeschichtung zur Verfügung gestellt, welche mindestens eine Wärmedämmschicht und eine einen thermographischen Leuchtstoff enthaltende Leuchtstoffschicht umfasst. Der thermographische Leuchtstoff ist ausgewählt aus der Gruppe: YAG:Tm, YSZ:Dy, GZO:Dy, GZO:Tm, YAG:Sm, EZO.
