The invention discloses an Sr3La0.9Eu0.1(VO4)3 fluorescent temperature probe material used for temperature detection and a preparation method for the fluorescent temperature probe material. The fluorescent material is provided with two emission peaks with a relatively wide spacing, wherein the emission peaks are positioned on 515 nanometers and 613 nanometers respectively, so that the screening for a fluorescent signal is facilitated; moreover, a ratio of the two peak intensities is fiercely changed along with the temperature, the temperature sensitivity is improved by nearly one order of magnitude relative to the fluorescent temperature probe material which is researched at present. Therefore, the Sr3La0.9Eu0.1(VO4)3 fluorescent temperature probe material is a fluorescent temperature probe material with good application prospect.
