Previously obtained and certified HfO2 based samples were investigated by two Raman spectrometers with different wave source. Stokes reflexes have to be independent of the laser frequency so they were distinguished by comparison of different laser results. For the first time the dependence of Stokes lines frequencies on the cation radii of dopants was observed. Frequencies monotonically varied with the ratio of cation-dopant to hafnium radii changes. All non-Stokes reflexes are considered as photoluminescence. They were compared with both the literature data on luminescence of REM cations and the experimental results on zirconia-based materials intrinsic photoluminescence, which was a property of its point defects. Intrinsic photoluminescence is observed for the first time on hafnia-based materials. Keywords: Raman spectroscopy, luminescence, hafnia with cubic structure, REE.

“…The observed effects have low intensity and increased sensitivity to experimental conditions [34], and, according to it-seems that due-to this they have been poorly known.

“…Consequently, we have used this material, commonly known as yttria stabilized zirconia (YSZ), as a crystal matrix for the preparation of lanthanide-based luminescence materials. [12,21] Nevertheless, even with stabilization of the high temperature phase, there are still difficulties in preparing high quality crystals, because of the high melting point of ZrO 2 (2716 °C), and the associated difficulty in finding a suitable crucible material. This problem has now been overcome by using the optical floating zone method, which can produce crystals of YSZ with good optical transparency and few defects.…”

Blue, green, and red emissions through upconversion and energy transfer processes are investigated as a function of the Tm3+ concentration in Tm/Er/Yb triply doped yttria stabilized zirconia (YSZ) crystals upon excitation at 980 nm. YSZ doped with 0.075–0.250 mol% Tm2O3, 1.50 mol% Er2O3, and 2.00 mol% Yb2O3 are prepared by the optical floating zone method, and confirmed to be in the cubic phase by X‐ray diffraction. The blue emission corresponds to the Tm3+ 1G4→3H6 transition, and is produced through a three‐photon process, whereas the green and red light are emitted through two‐photon processes from the Er3+ 2H11/2→4I15/2 and 4S3/2→4I15/2 transitions for green and the Er3+ 4F9/2→4I15/2 transition for red. However, interactions between the different lanthanide ions is a factor in determining the overall color of these triply doped crystals, and this is not simply a summation of the results from the singly doped systems, so this mechanism of energy transfer is discussed in detail. The CIE color chromaticity coordinates for the present samples under excitation at 980 nm approach (0.39, 0.55), which is in the yellow‐green region.
