Abstract: The perfect energy level overlap of 2H11/2, 4S3/2, and 4F9/2 in Er3+ ions with those of 5F3, 5F4/5S2, and 5F5 in adjacently codoped Ho3+ ions allows efficient interenergy transfer. Therefore, in addition to routine activators,…

Abstract: In this paper, we report the temperature and rhodamine B (RhB)-concentration sensing behavior of Ag/ZnO/Er3+:YbMoO4 composite films based on the fluorescence intensity ratio (FIR) of two green upconversion (UC) emissions which are ascribed to the…

Abstract: A series of lanthanide-based metal-organic frameworks (Ln-MOFs) with significantly improved and tunable upconversion emissions were prepared. Y-MOFs co-doped with Yb3+/Er3+ ions have exhibited characteristic upconversion emissions at 520, 545, and 658 nm under 980 nm…

Abstract: Upconversion broadband white light emission driven by low-power near-infrared (NIR) lasers has been reported for many materials, but the mechanisms and effects related to this phenomenon remain unclear. Herein, we investigate the origin of laser-induced…

Abstract: Er3+-Yb3+ co-doped titanium dioxide upconversion nanoparticles were synthesized by Sol-gel method. White upconversion emissions were observed after excitation of nanoparticles with 980 nm Near-Infrared laser diode. Upconversion emissions consist of red (640-690 nm), green (520-570…
