“…Investigating whether this poses a problem for the wavelength shifters and measuring the light yield of the 3D-printed scintillators are the main subjects of the studies presented here. Other 3D-printing techniques, for comparison, require an additional step to produce suitable scintillator filament [5,6] or resin [7,8] first.…”

Plastic scintillators are widely used in particle physics experiments. Additive manufacturing techniques allow the production of parts with free shapes and, depending on the application, direct integration with other detector components. This opens up new possibilities for the development of, for example, trigger and veto systems or 3D-segmented detectors like high-granularity calorimeters utilizing structured scintillators with diffuse reflective subdivisions. ARBURG Plastic Freeforming (APF) devices feature the processing of several different granulates at the same time including in-line drying, melting points up to 350°C and high-frequency droplet discharging. The usage of granulates to 3D-print plastic scintillators has the advantage that original materials produced without plasticizers or polymerization starters can be used. However, it must be investigated whether the materials degrade under the high process temperatures to which they are exposed. Achieving high transparency and surface quality are further challenges, as with other techniques. Using the APF process, we have 3D-printed scintillator samples made from granulate based on polystyrene. We have used both commercial granulate with POPOP and p-terphenyl wavelengthshifting additives as well as self-made granulate with PPO and bis-MSB. With these samples we have performed several measurements to evaluate their performance with regard to transparency, fluorescence behavior, decay time and light-yield. We present the results by comparison with reference scintillators and polymethylmethacrylate samples.

“…The development of garnet-based LED devices can allow for better control of light scattering and the minimization of optical losses [9]. Garnet NPs can also be used for composite scintillation materials production in combination with such technologies as spin coating, thermal polymerization, chemical bath deposition, inkjet printing, 3D printing, and ceramization [7,10,11]. Garnet NPs have been mostly fabricated using chemical methods like sol-gel, solvothermal, co-precipitation, hydrothermal, combustion, photo-induced synthesis, etc.…”

The application of a pulsed laser ablation technique for the generation of cerium-doped garnet nanoparticles in liquids is investigated. The morphological and optical properties of the obtained nanoparticles are demonstrated. Features introduced by the single crystals of Gd3Al2.4Ga2.6O12:Ce3+, Lu3Al5O12:Ce3+, and Y3Al1.25Ga3.75O12:Ce3+ from which the nanoparticles are generated, as well as the parameters of a liquid media on the garnet nanoparticle generation are experimentally studied using TEM and UV-Vis spectroscopy methods. It is shown how the size, shape, and internal structure of the nanoparticles are related to the external laser ablation conditions, as well as to the laser melting processes of NPs in the colloidal solutions. This work provides important information about the generated nanoparticles, which can be used as building blocks for specially designed structures with predetermined optical properties.
