FE²�?ZNS CRYSTAL - AN OVERVIEW

KLuS two one crystal samples undoped and doped by using a small (five %) or superior (38 %) concentration of trivalent thulium or ytterbium ions have been synthesized in the form of skinny hexagonal plates. The low phonon energy (�?20 cm ⁻�?) was confirmed employing Raman spectroscopy. Samples ended up analyzed also by making use of optical a
