“…The optical quality of the spinel ceramics is closest to the theoretical transmittance limit, compared with the printed silica glass and YAG ceramics. [ 11–13,15,16,21,28–33 ] The printing resolution is much higher than that of many other printed transparent materials. Therefore, our work has simultaneously circumvented the two bottlenecks in optical transparency and printing resolution of the state‐of‐the‐art 3D printing techniques of transparent ceramics and glass, thus enabling the harnessing of the advantages of the unique physical properties of spinel ceramics and the flexibility of SLA 3D printing technique to create various advanced spinel based optics and catalyst supports for engineering applications.…”

3D printing of transparent ceramics has attracted great attention recently but faces the challenges of low transparency and low printing resolution. Herein, magnesium aluminate spinel transparent ceramics with transmittance reaching 97% of the theoretical limit are successfully fabricated using a stereolithography‐based 3D printing method assisted by hot isostatic pressing and the critical factors governing the transparency are revealed. Various transparent spinel lenses and microlattices are printed at a high resolution of ≈100–200 µm. The 3D printed spinel lens demonstrates fairly good optical imaging ability, and the printed spinel diamond microlattices as a transparent photocatalyst support for TiO2 significantly enhance its photocatalytic efficiency compared with its opaque counterparts. Compared with other 3D printed transparent materials such as silica glass or organic polymers, the printed spinel ceramics have the advantages of broad optical window, high hardness, excellent high‐temperature stability, and chemical resistance and therefore, have great potential to be used in various optical lenses/windows and photocatalyst supports for application in harsh environments.

“…Currently, a signi cant attention has been focussed on the photonic glasses which are having several applications in laser generation, optical telecommunication, solid state lighting, integrated photonic chips and smart windows for energy savings [1][2][3][4][5]. Furthermore, lathanide activated luminescent glasses have some assorted advantages over the conventional phosphors employed in the white light emitting diodes such as better heat resistance, less power consumption, superior luminous properties and their ease of production.…”

A series of singly and doubly Ce3+ / Eu3+ doped lithium borate (LBZ) glasses have been synthesized via melt quenching. XRD and SEM analysis confirmed the non-crystalline nature of glasses. The emission spectrum of Ce3+: LBZ glass reveals an extensive blue emission band at 447 nm (5d→4f) by exciting with 350 nm. An intense excitation band noticed at 393 nm (7F0→5L6) of Eu3+ in Eu3+: LBZ glass, which is associated with the excitation wavelength of near-ultraviolet LED chip. The luminescence spectra of Eu3+ disclose a strong red emission at 612 nm (5D0→7F2) excited with 393 nm. By raising the content of Eu3+ ions, the luminescence features were embellished remarkably. However, the dazzling red emission intensity of Eu3+ was ameliorated by the insertion of Ce3+ ions in co-activated glass due to energy transmission. Spectral overlap, fluorescence studies, decay dynamics, CIE coordinates and color purity corroborated the transfer of energy from Ce3+ to Eu3+. The CIE color coordinates of the optimized (1.0 Ce3+ + 1.0 Eu3+) co-doped glass has been shifted to the white light region. In view of these spectral features, 1.0 mol % Ce3+ + 1.0 mol % Eu3+: LBZ glass could be suggested as a promising candidate for the white light applications.

“…[ 26 ] Liu et al developed multicolor luminescent glass objects by doping different rare earth ions in different parts of a silica glass. [ 27 ] Besides, perovskite quantum dots were also employed inside a transparent glass and showed reversible luminescence properties, suggesting potential applications such as information encryption and 3D artwork. [ 28 ] Furthermore, 3D printing for white light lampshades has utilized room temperature phosphorescence from organic species.…”

The environmentally friendly and low‐priced CaYAlO4:Tb3+ nanophosphors are combined with good optically transparent materials for the application in 3D printing. For ultraviolet (UV) light‐emitting diode excitation, CaYAlO4:Tb0.07Cey and CaYAlO4:Ce0.05Tbx nanophosphors are prepared by a sol–gel route and systematically studied for optimal excitation at 380 nm to give strong green emission to which human and aquatic animals eyes are generally sensitive. This is benefited from the dipole and spin allowed transition of Ce3+ and the 92.5% efficient energy transfer from Ce3+ to Tb3+ in this host. Polydimethylsiloxane, with 92% transmittance in the visible spectral region, is a valid choice to make the shaped artwork by a templating method, combined with the nanoparticles to give a uniform distribution, as determined by X‐ray microcomputed tomography. Polylactic acid is also employed to create a frog artwork by the fused deposition modeling method. The final 3D‐printed colorful artwork is displayed herein together with that produced by the templating method under different light source excitation to suggest a novel expression of aesthetic concepts and a potential application in the future marine environment such as a lamp to attract aquatic animals or a buoy to guide ships.
