Graphical abstract: The sensor sensitivity as a function of the temperature of erbium and holmium doped fluoroindate glasses. A wide temperature range from 20 K to 425 K is covered with a sensitivity larger than 0.0005. Highlights: {yields} The FIR technique has been carried out in fluoroindate glass sample. {yields} The Er doped fluoroindate sample has a maximum sensitivity of 0.0028 K{sup -1} at 425 K. {yields} The Ho doped fluoroindate sample has a maximum sensitivity of 0.0036 K{sup -1} at 59 K. -- Abstract: The fluorescence intensity ratio technique for two fluoroindate glass samples has been carried out. The green emissions at 523 nm and at 545 nm in a 0.1 mol% of Er{sup 3+} doped fluoroindate glass was studied in a wide range of temperature from 125 K to 425 K with a maximum sensitivity of 0.0028 K{sup -1} for 425 K. In a sample doped with 0.1 mol% of Ho{sup 3+} the emissions at 545 nm and at 750 nm were analyzed as a function of temperature from 20 K to 300 K obtaining a maximum sensitivity of 0.0036 K{sup -1} at 59 K. Using both fluoroindate glass samples a wide temperature range from 20 K to 425 K is easily covered pumping with two low-cost diode laser at 406 nm and 473 nm.
