Chlorophane is nothing but fluorspar or Calcium fluoride. It gives off visible light when heated referred to as thermoluminescence just as you mentioned. Depends on what you want to use the material for? It is typically used in radiation detectors. Lithium fluoride is also a thermoluminescent material. Fluorspar is naturally occurring on earth. it will luminesce on light heating but it is weak and you would have to do the experiment in the dark for best results
