“…This change could be related to the strong dependence of the 4f-5d transition state of Tb 3+ ions from the environment of the ions. 20 Figure 4 (right) shows the 5 Figure 5. The trend observed is in contrast with previous studies 16 17 which report a maximum intensity at concentration of about 2 at%.…”

Y2O3:Tb3+ nanoballs were synthesized via the urea homogeneous precipitation method (UPM). The resulting Y2O3:Tb3+ phosphors were characterized by X-ray diffraction (XRD), scanning electron microscopy, ultraviolet-visible (UV-vis) absorption spectra, and general photoluminescence spectra. The particle sizes estimated using X-ray diffractometry and scanning electron microcopy were about 50-200 nm. The emission intensity of the Y2O3:Tb3+ was low when the doping concentra- tions of Tb3+ were higher. The optimum concentration of Tb3+ for synthesis of Y2O3:Tb3+ nanocrystals is 1%.

“…As shown in 5 scheme 1 and Fig. [31][32][33] The red emission is obtained by the transition 4 F9/2 → 4 I15/2. Then Er 3+ ions are excited from the 4 I15/2 ground state to the 4 I11/2 excited state via Yb 3+ → Er 3+ energy transfer.…”

This study reported the significantly improved Raman enhancement ability of silver nanoparticles (Ag NPs) by decorating them on single NaYF4:Yb,Er@SiO2 core-shell particles (UC@SiO2@Ag) under a 785 nm excitation. The optimal thickness of the silica shell can be easily obtained by adjusting the amounts of TEOS, which is the crucial element to balance the upconversion and the formation of a hot spot by Ag NP aggregation. This substrate revealed highly reproducible properties, which is crucial to the practical application of SERS technology. This substrate exhibited an excellent sensitivity for methylamphetamine detection under near-infrared excitation. The advantages of NIR excitation in our SERS sensing open up a new application field of UC-noble metal composites, and also promise a new research direction for the synthesis and applications of SERS-active nanostructures.
