1. A thermo-optical analysis system, comprising:
a thermoluminescence sensor comprising:
a thermo-responsive polymer composition, and
a sealed transparent container for the thermo-responsive polymer composition, wherein the thermo-responsive polymer composition takes up more than 90 vol % of an inner space of the sealed transparent container;
a photomultiplier tube (PMT) operatively configured to the thermoluminescence sensor;
a heat transfer plate in thermal communication with the thermoluminescence sensor;
wherein the heat transfer plate is configured to transfer thermal energy between a thermal source and the thermoluminescence sensor;
wherein the thermo-responsive polymer composition comprises:
a curcumin oil;
a cyano derivative of poly(phenylenevinylene) of formula (I)

OG Complex Work Unit Chemistry
wherein at least a portion of the cyano derivative of poly(phenylenevinylene) is in the form of an exciplex with the curcumin oil, wherein the exciplex has formula (II)

OG Complex Work Unit Chemistry
wherein R1, R2, R3, and R4 are each independently selected from the group consisting of C1-C9 alkyl, C1-C9 alkenyl, C2-C9 alkynyl, C1-C6 alkyloxy-C1-C6 alkyl, C1-C6 alkylthio-C1-C6 alkyl, and C1-C6 alkylamino-C1-C6 alkyl, wherein each of the carbon-containing radicals is optionally substituted with one or more halogen atoms, and wherein n is a positive integer.
