FASCINATION ABOUT FE²�?ZNS CRYSTAL

KLuS two one crystal samples undoped and doped using a lower (five %) or substantial (38 %) focus of trivalent thulium or ytterbium ions were synthesized in the form of skinny hexagonal plates. The small phonon energy (�?20 cm ⁻�?) was confirmed applying Raman spectroscopy. Samples have been researched also through the use of optical absorpti
