“…Based on the density of states we obtain a band-gap of 5.0 eV for Er 2 SiO 5 and 5.2 eV for Er 2 Si 2 O 7 . This is in agreement with the experimental estimation of 4~5 eV for Er 2 SiO 5 [7]. For Er 2 SiO 5 , two Er atoms have a very similar DOS.…”

Rare earth silicates (RE2SiO5 or RE2Si2O7; RE=Er, Lu, Y, Yb etc.) possess a low silica activity and good thermal stability, making them good candidates for EBC top coating materials. We have performed first-principles total energy calculations for the Er2O3-SiO2 pseudo binary system. The crystal lattice parameters and internal atomic coordinates of Er2SiO5 and Er2Si2O7 are optimized, and the electronic structure and formation enthalpies are calculated. The present study provides a theoretical basis for exploring practical applications of the materials.

“…The photoluminescence phenomena of ultraviolet light by lanthanide doped materials has attracted much more attention in the present days due to their potential applications, such as lightemitting devices, optoelectronics, medical diagnostics and sensor [7][8][9][10][11][12]. Erbium oxide has been intensively investigated for different technological purposes, such as color display, data storage, biological diagnosis, infrared detection, and temperature sensor [13][14][15][16]. It also plays an important role in a preparation of novel light -emitting materials [17][18].…”

Er3+-doped ZnO – BaO – TeO2 glasses with the formula (80-x)TeO2–15ZnO–5BaO–xEr2O3 were fabricated using melt quenching technique. The 5 glass samples with different concentrations of Er2O3 were prepared under atmospheric pressure. The samples were investigated on their properties: density, molar volume, absorption spectra and photoluminescence. Density was increased with an increase in Er3+ content. The molar volume trend is in the opposite way to that of the density. The absorption bands are assigned as absorptions from the 4I15/2 ground state to the 4F7/2, 2H11/2, 4S3/2, 4F9/2, 4I9/2, 4I11/2 and 4I13/2 levels. All absorption bands are increase with increasing content of Er3+. The photoluminescence spectra were measured with 980 nm light pumped by flash lamp. The spectra trends to increase with increasing concentration of the dopant.
