Technical specifications
Phase change materials (PCM) with fluorescent dyes. At room temperature the dyes are aggregated in a rigid matrix and in most of the cases no fluorescence is observed (unactivated-cold state). After heating above the melting point of the PCM, the dyes dissolve and they disaggregate shinning different colors (activated-warm state).
