Photoluminescent Nanoparticle Surfaces: The Potential of Alkaline Earth Oxides for Optical Applications
Source abstract
Abstract
The surfaces of alkaline earth oxides emit bright, colored light and have potential as thermally stable inorganic phosphors with adsorption-dependent optical properties. The doping of thermally stable MgO nanocubes with low-coordinated BaO surface elements (see figure) clearly demonstrates that chemical manipulation of the solid–gas interface provides an efficient means to adjust the optical properties of powders in controlled gas atmospheres.

27. 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.
28. Scattering effects render the quantification of particles reached by excitation light and those sampled with respect to PL emission impossible.

30. 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 BaxMg1–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.
