    We report on a new thermochromic material containing a europium complex for thermal sensing through its fluorescence response to temperature. The ratio between the strong luminescence peak of europium (III) and a side band emission is employed as a new probe for optical sensing of temperature. The ratio is observed to follow an Arrhenius-type dependence with temperature. Based on these results we developed a thermal probe based on a segment of luminescent thermometer optically cemented to the tip of a PMMA fibre.
