“…[31][32][33][34] The attention of the present study is paid to the Er 3+ -doped Yb 3 Ga 5 O 12 nanocrystalline garnet as deepred upconversion emitting phosphor prepared by combustion technique. Many works on Yb 3 Ga 5 O 12 garnets are devoted to the study of magnetic properties, [38][39][40][41] dielectric properties, 42 and applicability in thermophotovoltaics. 43,44 However, only a few studies deal with photoluminescence in RE-doped 45 or TM-doped 46 Yb 3 Ga 5 O 12 nanocrystalline garnets.…”

The nanocrystalline single-phase Er 3+ -doped Yb 3 Ga 5 O 12 garnets have been prepared by the sol-gel combustion technique with a crystallite size of ≈30 nm. The presence of Yb 3+ in garnet hosts allows their efficient excitation at the ≈977 nm wavelength. The Er 3+ doping of Yb 3 Ga 5 O 12 garnet host results in deep red Er 3+ : 4 F 9/2 → 4 I 15/2 upconversion photoluminescence (UCPL) emission. The dominance of the red UCPL emission over the green Er 3+ : 4 F 7/2 / 2 H 11/2 / 4 S 3/2 → 4 I 15/2 component was investigated using the measurement of the steady-state and timedependent Er 3+ and Yb 3+ emission spectra in combination with the powerdependent UCPL emission intensity. The proposed upconversion mechanism is discussed in terms of the Er 3+ → Yb 3+ energy back transfer process as well as Yb 3+ (Er 3+ ) → Er 3+ energy transfer and Er 3+ ↔ Er 3+ cross-relaxation processes. The studied Er 3+ -doped Yb 3 Ga 5 O 12 garnet may be utilized as a red upconversion emitting phosphor.
