The distribution of rare earth ions in a γ-Ga2O3 nanocrystal-silicate glass composite and its influence on the photoluminescence properties

The partitioning of rare earth ions (REs: Yb3+, Er3+, Eu3+ and Nd3+) in γ-Ga2O3 nanocrystals (NCs) precipitated in a nanostructured silicate glass ceramic is revealed, and the enrichment of REs in the NCs (bulk doping) rather than on the interfaces between the NCs and the surrounding glassy phase (surface doping) is differentiated.
