THE 5-SECOND TRICK FOR FE²�?ZNS CRYSTAL

KLuS 2 one crystal samples undoped and doped which has a low (five %) or substantial (38 %) concentration of trivalent thulium or ytterbium ions were synthesized in the form of thin hexagonal plates. The reduced phonon energy (�?20 cm ⁻�?) was confirmed using Raman spectroscopy. Samples ended up examined also by making use of optical absorpti
