“…In general, effective mass approximation results in overestimation of the thermalization length in most crystals since group velocities and mobilities of hot carriers are overestimated. A set of papers are devoted to the description of the next stage, namely, the interaction and the recombination of charge carriers, which are described using either classical rate equations [185]- [187] or kinetic Monte Carlo calculations [188], [189]. This approach to thermalization stage makes a further step toward developing a toolkit to estimate scintillators properties [186].…”

This paper presents new developments in inorganic scintillators widely used for radiation detection. It addresses major emerging research topics outlining current needs for applications and material sciences issues with the overall aim to provide an up-to-date picture of the field. While the traditional forms of scintillators have been crystals and ceramics, new research on films, nanoparticles, and microstructured materials is discussed as these material forms can bring new functionality and therefore find applications in radiation detection. The last part of the contribution reports on the very recent evolutions of the most advanced theories, methods, and analyses to describe the scintillation mechanisms.

The location of the lanthanide ground states with respect to the host valence band or to the vacuum level always follow characteristic zigzag patterns with the number of electrons q in the 4f orbital. The patterns that are used today evolved over the years by combining experimental data from different techniques, and they are in first approximation independent on the type of compound. Here we will demonstrate that the ground state locations for Pr 3+ and Tb 3+ in the currently used pattern for trivalent lanthanides appear, when inspected on the ± 0.1 eV accuracy level, not consistent with two independent sets of experimental data. One set is from data on the intervalence charge transfer (IVCT) from Pr 3+ and Tb 3+ to the conduction band (CB) observed in luminescence excitation spectra. The other set is from the release of holes from Pr 4+ and Tb 4+ to the valence band observed in thermoluminescence (TL). In addition to the inconsistency, TL based evidence for a slight compound dependence in the characteristic zigzag patterns is found.
