Special Issue Information
Dear Colleagues,
Recent progress in luminescent and scintillating materials has opened new opportunities for the development of high-performance detectors applied in radiation physics, radiotherapy, and nuclear medicine. Current research focuses on oxide-based single crystals, epitaxial structures, and composite scintillators optimized for accurate detection, imaging, and dosimetry of ionizing radiation.
Particular attention has been devoted to doped simple and mixed oxide systems in both bulk and epitaxial forms, including heavy compounds such as YAG, LuAG, and GAGG garnets and their combinations; Gd–Lu-based perovskites; Y–Lu–Gd orthosilicates; and La–Gd–Y pyrosilicates, as well as “light” materials such as Al₂O₃ (sapphire) and MgAl₂O₄ (spinel). Synthesized using advanced crystal growth methods including Czochralski, Bridgman, micro-pulling-down (MPD), and liquid-phase epitaxy (LPE), these materials exhibit high optical transparency, radiation hardness, and tunable scintillation decay kinetics. Their fast decay times, high light yields, and excellent thermal stability make them promising candidates for real-time radiation monitoring, beam quality control, and in vivo dosimetry in external beam and brachytherapy applications.
Recent developments have also demonstrated the potential of compact scintillation detectors integrated with optical fiber readout and silicon photomultipliers, enabling precise, real-time dose measurements under clinical conditions. Parallel advances in optically stimulated luminescence (OSL) detectors and composite multilayer architectures have further expanded the versatility of these materials, allowing simultaneous detection of mixed radiation fields and enhanced sensitivity through interface engineering.
Collectively, these advances underline the multifunctionality, structural robustness, and broad applicability of garnet-, perovskite-, silicate-, and Al₂O₃–MgAl₂O₄-based scintillators and detectors. Their integration into next-generation detection systems bridges fundamental luminescence research with practical innovations in medical imaging, clinical dosimetry, and radiation physics instrumentation.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Materials is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
