THE 2-MINUTE RULE FOR FE²�?ZNS CRYSTAL

KLuS 2 solitary crystal samples undoped and doped using a small (5 %) or large (38 %) concentration of trivalent thulium or ytterbium ions were synthesized in the form of slim hexagonal plates. The small phonon Vitality (�?20 cm ⁻�?) was verified working with Raman spectroscopy. Samples ended up studied also by making use of optical absorptio
