THE 2-MINUTE RULE FOR FE²�?ZNS CRYSTAL

KLuS two solitary crystal samples undoped and doped by using a minimal (5 %) or large (38 %) focus of trivalent thulium or ytterbium ions have been synthesized in the shape of slender hexagonal plates. The minimal phonon Electrical power (�?20 cm ⁻�?) was verified working with Raman spectroscopy. Samples have been examined also by using optic
