Abstract: PURPOSE: To provide a thermal fluorescent composition having very little generation of pseudo-thermal fluorescence due to friction, by mixing conductive substances selected from among conductive metal oxides and sulfides with thermal fluorescent sustances.  
     CONSTITUTION: One or more conductive substances selected from conductive metal oxides (e.g. In 2 O 3 , ZnO, SnO 2 , etc.) and conductive metal sulfides (e.g. CdS, Cu 2 S, etc.) are mixed with thermal fluorescent substances (e.g. Li fluorescent substance activated by Mg, CaF 2  fluorescent substance activated by Mn, Mg 2 SiO 4  fluorescent substance activated by Tb, etc.) in a weight ratio of the former to the latter of 03:100W1:10. The mixing of the conductive substances provides thermal fluorescent substances having extremely little generation of the pseudo-thermal fluorescence due to friction.
