HOST-GUEST MATERIALS HAVING TEMPERATURE-DEPENDENT DUAL EMISSION

摘要

A composition is provided comprising a host material and a luminescent dopant. The composition exhibits dual luminescent emission peaks, one each for the host material and the luminescent dopant. The intensity of the emission peaks vary in intensity as a result of the changing temperature of the composition. This quality enables the composition to be used for ratiometric optical thermometry, including exemplary applications, such as in situ temperature sensing.
