description A probe for measuring tribological properties of materials, comprising a punch (50; 20), which includes a supporting body (52; 22) associated to a sliding end portion (51; 21) configured for sliding over the surface (30) of a material under test, said probe (10; 20) being associated to a detection device, which supplies at output a quantity (F) that is a function of the temperature (T±) of an interface between the sliding end portion (21) and the surface (30) of a material under test. According to the invention, said sliding end portion (21) configured for sliding over the surface (30) of a material under test is partially or totally made of fluorescent material, said probe (20) comprising a detection device, which supplies at output a quantity (F) that is a function of the temperature (T±) of an interface between the sliding end portion (21) and the surface (30) of a material under test and comprises optical means (14) for conveying, into said sliding end portion (21) a radiation (L), that is able to excite a fluorescence response (F) of said sliding end portion (21), in particular a laser radiation, and optical means (14) for collecting said fluorescence response (F) and conveying it to optical means (12) for detecting said fluorescence response (F).
