Radiative properties of GaSe and GaSe: Eu nanolamellar structures intercalated with Cd

Abstract

In this work the crystalline structure, surface morphology, photoluminescence (PL) and absorption spectra of CdSe-GaSe and CdSe-GaSe<Eu> composites are studied in the fundamental absorption band edge region. The studied composite contain CdSe and GaSe micro crystallites, and Eu3+ centers.
