    • In fact, surface exciton shifts are much larger than predicted by purely electrostatic concepts since significant contributions arise from quantum effects [11, Quantum-mechanical embedded-cluster calculations revealed that a particular absorption, band measured on AEO powders is actually composed of more than one electronic transition [15, Thus, excitation and absorption spectra should generally be assigned to surface topological features such as corners or edges rather than single ions of a specific coordination number

    • Increase of the Ba content is also associated with substantial changes in particle size and morphology. Higher Ba loadings can even lead to segregated and highly dispersed BaO that is supported on top of the BaxMg 1-xO nanocrystals. Concomitantly, the increase in. the surface concentration of particular and optically active surface sites is not expected to grow linearly with the overall Ba concentration
