“…[ 58 ] Other compositions have been reported using hybrid sol‐gel resins containing more than one metal or a metalloid, such as an acrylate siloxane complex with zirconium [ 59 ] or germanium. [ 60 ] Besides the monomers based on the silicon‐oxygen backbone, the availability of resins fostering fabrication of certain dopant‐free metal‐oxides (e.g., SnO 2 , [ 61 ] TiO 2 , [ 52,62 ] ZnO [ 55 ] ) may turn out to be advantageous for tuning the electronic and optical properties of the self‐miniaturized polycrystalline 3D‐printed structure.

“…Structures printed from the commercially available SZ2080 resin, which contains both Si and Zr, could thus far be transformed into inorganic glass‐ceramic composed of cristobalite and tetragonal zirconia. [ 59,60 ] In retrospect, silicon‐free zirconia can be the next steppingstone to manufacture well‐dispersed red‐emitting 3D‐printed ZrO 2 structures.…”

Such radiation has a long-lived 4f-4f transition, observed when evaluating lanthanides resulting in sharp narrowband emission. This light emission can be supported even when incorporating the lanthanide ion in a dispersion medium that acts as a host matrix with diverse functionalities. [7,9] Two host matrix types for lanthanide ions are identified, namely, organic [10] and inorganic materials. [7,11] Inorganic materials have high lattice-binding energy combined with rigidness; thus, in most cases, they show greater chemical and thermal resistance and photostability against continuous excitation than organic materials. [1,8] Highly crystalline inorganic host matrices are typically preferred to reduce point defects emissions. Hence, attention should be given to the crystallinity of the host material and the nonradiative multiphonon relaxation caused by the crystal lattice. [9] In practice, low phonon energy hosts are preferred to utilize the luminescent activator effectively. [7] However, the commonly used SiO 2 (≈1100 cm −1 stretching vibration) presents low lanthanide solubility, [12,13] leading to cluster formation at high dopant contents (10 18 cm −3 ), [14] quenching the lanthanide emission. [13] In photonics, a substitute for SiO 2 is ZrO 2 , which has relatively good transparency in the visible and infrared range and low phonon energy (≈470 cm −1 ). [12] ZrO 2 occurs in three polymorphs, tetragonal, monoclinic, and cubic, denoted t-ZrO 2 , m-ZrO 2 , and Implementation of more refined structures at the nano to microscale is expected to advance applications in optics and photonics. This work presents the additive manufacturing of 3D luminescent microarchitectures emitting light in the visible range. A tailor-made organo-metallic resin suitable for two-photon lithography is developed, which upon thermal treatment in an oxygen-rich atmosphere allows the creation of silicon-free tetragonal (t-) and monoclinic (m-) ZrO 2 . The approach is unique because the tailor-made Zrresin is different from what is achieved in other reported approaches based on sol−gel resins. The Zr-resin is compatible with the Eu-rich dopant, a luminescent activator, which enables to tune the optical properties of the ZrO 2 structures upon annealing. The emission characteristics of the Eu-doped ZrO 2 microstructures are investigated in detail with cathodoluminescence and compared with the intrinsic optical properties of the ZrO 2 . The hosted Eu has an orange−red emission showcased using fluorescence microscopy. The presented structuring technology provides a new platform for the future development of 3D luminescent devices.

Direct laser writing three-dimensional nano-lithography is an established technique for manufacturing functional 3D micro-and nano-objects via non-linear absorption induced polymerization process. In this Chapter an underlying physical mechanisms taking place during nano-confined polymerization reaction, induced by tightly focused ultra-short laser pulses, are reviewed and discussed. The special attention is paid on the effects that directly impact structuring resolution and minimum achievable feature size. Analysis of possible photo-initiation mechanisms as contributing multi-photon absorption and avalanche ionization in pre-polymers under diverse exposure conditions (wavelength, pulse duration) is presented. Feasible structuring of pure (non-photosensitized) and functional nanoparticles doped polymer precursors is justified and benefits of such materials/structures for microoptics, photonics and cell scaffolds are highlighted. The influence of temperature effects (induced by writing process itself or determined by ambient conditions) on polymerization process, observed in different pre-polymers under diverse exposure regimes is outlined. The further adjustment of the structuring resolution is possible via precise control of light polarization and diffusion assisted radical quenching. The work is concluded with a brief outlook on future challenges and perspectives related to refinement of 3D ultra-fast laser lithography fabrication process in the means of application of diverse post-processing methods and research into novel photo-curable materials including inorganic ones.
