Abstract Upconversion nanoparticles (UCNPs), incorporating lanthanide (Ln) dopants, can convert low‐energy near‐infrared photons into higher‐energy visible or ultraviolet light through nonlinear energy transfer processes. This distinctive feature has attracted considerable attention in both fundamental research and advanced optoelectronics. Challenges such as low energy‐conversion efficiency nonradiative losses limit the performance of UCNP‐based optoelectronic devices. Recent advancements including optimized core–shell structures, tailed Ln‐doping concentration, surface modifications show significant promise for improving stability. In addition, combining UCNPs with functional materials broaden their applications improve device performance, paving way innovation next‐generation paper first categorizes elaborates on various upconversion mechanisms UCNPs, focusing strategies to boost prolong luminescence. Subsequently, an in‐depth discussion that enhance expand functionality is provided. Furthermore, a wide range devices explored, multiple emerging neuromorphic computing are highlighted. Finally, existing challenges potential solutions involved developing practical considered, well outlook future technologies

Abstract Two‐photon polymerization 3D‐printing is a well‐known technique for fabricating passive micro/nanoscale structures, such as microlenses and inversely designed polarization splitters. The integration of light emitting nanoparticle (NP) dopants, quantum dots (QDs) rare‐earth doped nanoparticles (RENPs), into polymer resist would enable 3D printing active micro‐photonic devices, including sensors, lasers, solid‐state displays. Many NPs contain oleic acid ligands to prevent degradation, but oleate‐capped (oc‐NPs) tend agglomerate in nonpolar media despite the hydrophobicity ligand. This results an uneven distribution increased optical extinction. In this work, general approach proposed dispersing oc‐NPs commercial printable polymers. Controlled growth small carbon chains around achieved by functionalizing them with methyl‐methacrylate monomers. validated on RENPs (≈65 nm) CdSe/ZnS (≈12 using resists (IP‐Dip IP‐Visio).
