Proprietațile luminescente ale monocristalelor WSe2 și MoSe2 dopate cu ioni ai metalelor de tranziție (Cr) [Articol]

Abstract

Crystals were obtained by the CVT method, iodine as the transport agent. Incorporation of Cr and halogen, into crystals takes place during the growth. The research of near-infrared light PL has established the presence of two distinct spectral regions: the exciton region, located in the vicinity of the indirect banned, consisting of narrow lines and Analele științifice ale USM. Lucrări studențești phonon replicas, and broad band of deep levels, in the region of lower energies of PL spectra.
