Article Abstract
We report experimental studies of the bending strain impact on the upconversion processes in Yb, Er, and Mn co-doped BaTiO (BTO) thin films with mica as the flexible substrate. Bending strain induces strong enhancement and modulation of the upconversion emission in doped BTO thin films. Because the unshielded 3d configuration of Mn is more susceptible to crystal field changes, the introduction of an Mn ion further promotes the strain-induced modulation effect. The upconversion intensity is amplified by six times at bending strain ε = 1.83% in BTO:Yb/Er/Mn thin films. These results demonstrate the opportunity of rendering an upconversion emission through integrating lanthanide-doped ferroelectric films with flexible mica, especially by incorporating an Mn ion.

The synergistic effect of various ions with optical properties is an important method to regulate the Er ion upconversion luminescence process. However, the energy processes between them are complicated and difficult to separate, and it is challenging to clarify the results of each process when multiple ions are co-doped. Herein, a series of NaYF:Er were synthesized by the low-temperature combustion method, and the luminescence color of Er ions was modulated by doping Yb ions and Tm ions.

Near-infrared (NIR) synaptic devices are characterized by unique optical sensitivity and synaptic plasticity, possessing high potential to significantly broaden the visual spectrum accessible to humans. Moreover, these devices seamlessly integrate neuro-morphological computing with infrared optical communication, attracting significant attention for future low-power, high-efficiency neuromorphic visual systems. However, the irreversible optical response of most optical synapses under short-wavelength infrared light severely restricts the practical application of these devices.

Dendritic cell (DC)-based vaccines for solid tumors face major challenges, including limited tumor-specific antigens and immunosuppressive stroma. Here, we present a therapeutic nanovaccine (UCNP@MOF@MI@FM [UMMF]) composed of a DC/tumor fused cytomembrane-coated UCNP@MOF nanoparticle, co-loaded with a MutT homolog 1 (MTH1) inhibitor and combined with tetrahydrobiopterin (BH4). The fused membrane facilitates dual targeting to tumors and lymph nodes while enabling broad-spectrum tumor antigen presentation.

Ultraviolet (UV) light plays a central role in applications ranging from photochemistry to sterilization and water treatment. However, its low abundance in sunlight (∼10%) limits the direct solar use of UV-driven processes. Sensitized triplet-triplet annihilation upconversion (TTA-UC) offers a promising route to generate UV light from visible light under low-power excitation.
