Photoluminescent analysis of HfO 2 doped with Eu 3+ , as a function of temperature is reported. Samples were synthesized by hydrothermal method at 200 °C of temperature and 120 minutes of reaction time, using chlorides as raw materials. The HfO 2 was doped with trivalent europium ions (Eu 3+ ) at concentrations 1, 2, 3, 5 and 10 % atomic. X-ray diffraction (XRD) showed synthesized material crystallized in monoclinic phase characteristic of HfO 2 . Scanning electron microscopy showed presence of particles of smaller size than 100 nm forming agglomerates. Photoluminescent analysis at room temperature for sample doped with Eu 3+ (3%) display highest luminescent emission. Finally, photoluminescent analysis as a function of temperature, shown changes in luminescent intensity in 5 D 1 and 5 D 0 transitions, for 0 to 50 °C temperature range.
