WHAT DOES FE²�?ZNS CRYSTAL MEAN?

KLuS two solitary crystal samples undoped and doped which has a low (5 %) or high (38 %) focus of trivalent thulium or ytterbium ions ended up synthesized in the form of slender hexagonal plates. The low phonon Vitality (�?20 cm ⁻�?) was verified working with Raman spectroscopy. Samples ended up examined also through the use of optical absorp
