“…The luminescence properties of rare earth ions are impacted by interactions with the matrix and the phonon energy of the matrix in which they are held; a highly transparent single-crystal matrix allows light from a pump source to efficiently excite activated ions doped in the crystal. In this respect, a cubic zirconia crystal with a high melting point (2715 °C), excellent physical and chemical stability, high mechanical strength, and strong oxidation resistance is an excellent matrix material. − However, the cubic phase of ZrO 2 is only stable at high temperatures, although it can be stabilized at room temperature by doping with appropriate amounts of other oxides (e.g., 8.0 mol % Y 2 O 3 ). , Furthermore, the high melting point of zirconia makes the production of single crystals extremely difficult and represents a significant barrier to the development of zirconia optical crystals. In the present work, single crystals of cubic ZrO 2 codoped with Tm 2 O 3 , Ho 2 O 3 , and Yb 2 O 3 were successfully grown by the optical floating zone (OFZ) method.…”

Under excitation at 980 nm, Tm 3+ may emit ultraviolet, blue, and red light, and Ho 3+ may emit green light through multiphoton upconversion processes in Yb/Tm/Ho codoped materials. However, because the probability of the electron population of the higher excited state energy levels is much lower than that of the lower ones in multiphoton upconversion processes, it is difficult to observe the ultraviolet emission of Tm 3+ -doped single crystals under excitation at 980 nm. Here, we report that high-quality single crystals of cubic ZrO 2 codoped with Tm 2 O 3 , Ho 2 O 3 , and Yb 2 O 3 are successfully grown by the optical floating zone method, and ultraviolet emission at 308 nm was observed for the first time from multiphoton upconversion transitions in these highly transparent, low phonon energy single crystals under excitation at 980 nm. This result demonstrates the prospect of making ultraviolet solid-state lasers pumped by nearinfrared light. Moreover, bright white light was emitted from the single crystal prepared with 5.00 mol % Yb 2 O 3 , 0.75 mol % Tm 2 O 3 , 0.0075 mol % Ho 2 O 3 , 2.2425 mol % Y 2 O 3 , and 92.00 mol % ZrO 2 under excitation at 980 nm, and a bright solid white light source excited by a near-infrared light-emitting diode for practical use is presented.

Mechanoluminescent (ML) materials can exhibit visible-to-near-infrared mechanoluminescence when responding to the fracture or deformation of a solid under mechanical stimulation. Transforming mechanical energy into light demonstrates promising applications in terms of visual mechanical sensing. In this work, we synthesized the phosphor CaZnOS:Tb3+, Sm3+, which exhibited intense and tunable multicolor mechanoluminescence without pre-irradiation. Intense green ML materials were obtained by doping Tb3+ with different concentrations. Tunable multicolor mechanoluminescence (such as green, yellow-green, and orange-red) could be realized by combining green emission (about 542 nm), attributed to Tb3+, and red emission (about 600 nm) generated from the Sm3+ in the CaZnOS substrate. The tunable multicolor ML materials CaZnOS:Tb3+, Sm3+ exhibited intense luminance and recoverable mechanoluminescence when responding to mechanical stimulation. Benefiting from the excellent ML performance and multicolor tunability in CaZnOS:Tb3+, Sm3+, we mixed the phosphor with PDMS and a curing agent to explore its practical application. An application for visual mechanical sensing was designed for handwriting identification. By taking a time-lapsed shot while writing, we easily obtained images of the writer’s handwriting. The images of the ML intensity were acquired by using specific software to transform the shooting data. We could easily distinguish people’s handwriting through analyzing the different ML performances.
