Deep red upconversion photoluminescence in Er3+-doped Yb3Ga5O12 nanocrystalline garnet
Original language description
The nanocrystalline single-phase Er3+-doped Yb3Ga5O12 garnets have been prepared by the sol-gel combustion technique with a crystallite size of ≈30 nm. The presence of Yb3+ in garnet hosts allows their efficient excitation at the ≈977 nm wavelength. The Er3+ doping of Yb3Ga5O12 garnet host results in deep red Er3+: 4F9/2 → 4I15/2 upconversion photoluminescence (UCPL) emission. The dominance of the red UCPL emission over the green Er3+: 4F7/2/2H11/2/4S3/2 → 4I15/2 component was investigated using the measurement of the steady-state and time-dependent Er3+ and Yb3+ emission spectra in combination with the power-dependent UCPL emission intensity. The proposed upconversion mechanism is discussed in terms of the Er3+ → Yb3+ energy back transfer process as well as Yb3+(Er3+) → Er3+ energy transfer and Er3+ ↔ Er3+ cross-relaxation processes. The studied Er3+-doped Yb3Ga5O12 garnet may be utilized as a red upconversion emitting phosphor.
