Special Issue Information

Dear Colleagues,

Inorganic functional materials form the basis of the technical development of our civilization. Among their variety for this Special Issue, we selected those that are used to convert various types of energy into optical photons, the so-called materials for photonics. Such materials are typically used both as sources of optical radiation, for example, in illumination or generation of laser radiation, and as intermediate materials for working with photosensors, photovoltaic cells, etc. The set of the emitting or luminescent parameters of such compounds is formed by the composition of the atoms included in their structure.

The achievements of recent years in the fields of theory and technology of photonic materials make it possible to purposefully design their properties, which contributes to their rapid implementation in practice. The transition from single-and di-cation compounds to multi-ion (cationic and anionic) systems is particularly intriguing. It permits the construction at the atomic levels, making it possible to achieve simultaneous control of the band gap, the electron density structure in the zones adjacent to it, and the disposition of radiative levels inside it. This approach also provides the prerequisites for solving other problems, in particular minimizing optical radiation losses inside the material under various operating conditions.

A variety of developed and used methods for the preparation of multiionic compounds make it possible to quickly introduce such materials into equipment using materials for photonics.

Scintillation crystals Gd3Al2Ga3O12 (GAGG) are an excellent candidate for application in ionizing-radiation detectors because of their high radiation resistance, density and light yield. These crystals can be used in combination with lead tungstate (PbWO4 or PWO) crystals for the development of a new generation of electromagnetic calorimeter with advanced spatial and energy resolutions in a broad energy range. PWO crystals enable the accurate detection of high-energy photons, while GAGG crystals provide the possibility of precisely measuring photon energies, down to a few MeV. Different options for a composite electromagnetic calorimeter based on PWO and GAGG crystals are considered to optimize spatial and energy resolutions in a broad energy range (from 1 MeV to 100 GeV). In particular, different lengths of the GAGG section of the calorimeter are considered, from 0.5 to 10 cm. The separation of signals from photons and hadrons is also taken into consideration through the study of shower shape in the calorimeter. The optimization is based on Geant4 simulations, considering light collection as well as the use of different photodetectors and electronic noise. Simulations are verified with light yield measurements of GAGG samples obtained using radioactive sources and test beam measurements of the prototype of the PWO-based Photon Spectrometer of the ALICE experiment at CERN.
