FIELD: thermometers based upon physical or chemical changes.
SUBSTANCE: method comprises mounting a thermosensitive member on the object, measuring the luminescence spectrum, calculating the size of nanoparticles of the thermosensitive member before and after the object is exposed to high temperatures. The nanoparticles of difficulty fusible metal embedded into the aluminum base are used as a thermosensitive member. The size of nanoparticles of difficulty fusible metal indicates the value of temperature of the object.
EFFECT: expanded functional capabilities.
