Raman scattering study of phase transition in Lu 2 O 3 –Ta 2 O 5

“…These materials show promising applications in the fields of nuclear medicine and high energy physics due to their characteristic high efficiency output, fast response, and high density. [1][2][3][4][5][6] Rare earth tantalates are one type of high-density luminescence materials and the atomic numbers of Ta and rare earth ions are very high. Yb 3+ :RETaO 4 (RE = Gd, Y, Sc) have wide and strong absorption and emission bands, and these materials have attracted attention due to their promising applications in both ultrashort and tunable lasers.…”

Photoluminescence of rare-earth ion (Eu 3+ , Tm 3+ , and Er 3+ )-doped and co-doped ZnNb 2 O 6 for solar cells

“…Rare-earth ion-doped materials, which are used as light converter layers for enhancing the photovoltaic efficiency of solar cells, are currently attracting extensive interest. [1][2][3] Although these solar cells could fill the energy gap left by fossil fuels, the transmission of sub-bandgap light still limits the photovoltaic efficiency of solar cells. In particular, the dyesensitized solar cell only has high absorption in the visible range of 400 nm-700 nm, due to its wide bandgap of about 1.7 eV-1.8 eV.…”

High‐Temperature Phase Relations in the Lu2O3–Ta2O5 System

“…In the recent years, some new scintillator materials have been paid on great attention. These materials show a promising application in the fields of nuclear medicine, high‐energy physics, etc., due to their high luminescent efficiency, fast decay, and high density . Rare‐earth tantalates are high‐density phosphor, whose rare earth and Ta ions have large atomic numbers and lead to a high‐stopping power to the high‐energy particles and rays.…”
