Upconversion luminescence of NaYF4: Yb3+, Er3+ for temperature sensing
TL;DR: In this paper, the temperature dependence of the fluorescence intensity ratio (FIR) of emission bands centered at 525 and 545 nm was measured in the temperature range of 160-300 ǫ K under excitation of a 980-nm diode laser.
Journal ArticleDOI
Thermometric and optical heating bi-functional properties of upconversion phosphor Ba5Gd8Zn4O21:Yb3+/Tm3+
TL;DR: Yb3+/Tm3+ co-doped Ba5Gd8Zn4O21 upconversion (UC) phosphors with thermometric and optical heating properties were successfully prepared by a sol-gel process, and crystal structures of all samples were examined by X-ray diffraction.
Journal ArticleDOI

TL;DR: Experimental results on high-fidelity optical initialization, efficient coherent manipulation and optical readout of a single-electron spin of Ce(3+) ion in a yttrium aluminium garnet crystal suggest that cerium electron spins can be exploited as an interface between photons and long-lived nuclear spin memory.
Journal ArticleDOI
Optical thermometry based on upconversion luminescence in Yb3+/Ho3+ co-doped NaLuF4
TL;DR: In this paper, a short wavelength upconversion luminescence of Ho3+ was investigated for temperature sensing with fluorescence intensity ratio (FIR) technique in Yb3+/Ho3+ co-doped β-NaLuF4 hexagonal microprisms synthesized by hydrothermal method.
