Synthesis, structural and optical characterization of Nd: YAG powders via flame spray pyrolysis

Atomic layer deposition of Er-doped yttrium aluminum gallium garnet nanofilms with tunable crystallization and electroluminescence properties

“…32 Here the grain sizes are calculated from the broadening of the diffraction peak (420) of the Er-YAGG nanofilms annealed at different temperatures using Debye–Scherrer's formula, D = kλ / β cos θ , where D is the calculated crystalline size on the nm scale, k = 0.94, λ Cu = 0.15406 nm, β is the full-width at half-maximum (FWHM) of the peak in radians corrected from instrumental broadening, and θ is the diffraction angle. 33 The values of β and D of the main diffraction peaks [corresponding to the crystal plane (420)] of the different Er-YAGG nanofilms are summarized in Table 1, and the trends of β and D with different Al contents for the Er-YAGG nanofilms annealed at 1000 °C are illustrated in Fig. 1(d).…”

A New Chemical Mechanical Slurry for Polishing Yttrium Aluminium Garnet Material with Magnesium oxide, Sodium Metasilicate Pentahydrate and Zirconium Dioxide Abrasive Particles

“…The XPS spectral descriptions as shown in Fig. 8 combine with the binding energy reference parameters listed in Table 3 [25,26] show that different elements exist on the Y3Al5O12 workpiece surface before and after polishing by CMS-4. After polishing by CMS-5, the results of XPS spectrum analysis with Mg 1s and Si 2p for the Y3Al5O12 workpiece are as described in Fig.…”

Luminescent Materials Based on Aluminates: A Review

“…Various methods for ceramic fabrication of YAG and the problems involved are summed up by several authors. [318][319][320] Though the powders are obtained at relatively low temperatures, the transparent ceramic fabrication still requires temperatures as high as 1700 °C. [321] Sintering under high pressure (8 GPa) could bring this down to 450 °C.…”
