Transparent ceramics have become available in useful sizes for a variety of applications within the past 15 years thanks to improved understanding of sintering phenomena on the nanoscale.1,2 While traditional ceramics may comprise single or multiple crystalline and amorphous mineral phases and are typically translucent or opaque to light, modern optically transparent ceramics are fully dense monoliths of micron-scale (or smaller) crystallites, in most cases formed from pure-phase cubic crystal structures.

IAEA International Atomic Energy Agency. Gamma-ray spectroscopy using scintillation detectors is one of the most important measurement methods used in the various applications of nuclear science and its research. Sci. In harsh environments, such as nuclear-fuel-rod pools or for oil-well logging, a rugged material, such as a transparent ceramic, is desirable. Instrum. Nucl. IEEE Trans. Physical processes such as particle acceleration, accretion, and nucleosynthesis are observable and are at play in the most violent phenomena of the Universe (e.g., supernovae, relativistic jets, gamma ray bursts). For transparent ceramic scintillators, widespread use will depend on demonstrated performance enhancements such as high light yields and uniformity of response, and on the economics of industrial fabrication. 12: 543.

To calibrate a gamma ray scintillation spectrometer, using gamma rays of known energy, and use it to measure the energy of an "unknown" gamma ray. The elpasolite crystals with Ce3+ dopants are promising for these endeavors due to their modest light yield and extremely good proportionality when excited by the gamma ray. The spectrometer's detector consists of a CsI (Tl) scintillator and silicon photomultiplier (SiPM) and its readout is facilitated by an Arduino UNO. It uses materials to emit photons upon encountering a nuclear particle or radiation (L'Annunziata, 2012, VOSE, 1980). https://doi.org/10.1117/12.857357, D. Xu, Z. ; Pu, N.W.
