A scattered wave model of electronic structure of Eu2+ in BaMgAl10O17 and associated excitation processes

Characterisation of the luminescence properties of BAM:Eu2+ particles as a tracer for thermographic particle image velocimetry

“…These sites might have different populations, and the saturation threshold could potentially be increased. The aforementioned studies [21,23,[30][31][32] agree on the existence of at least three sites named Beevers-Ross (BR), antiBeevers-Ross (aBR) and mid-Oxygen (mO). However, the position, strength, and width of the absorption band of each site are still not completely clear.…”

“…It is also proposed that the very broad and irregular excitation spectrum above 200 nm shown in Fig. 9 is composed of the absorption bands of the individual sites [30]. The excitation below 200 nm is attributed to host lattice absorption.…”

“…Emission collected at 460 nm. Reproduced with permission from [30] Many studies suggest that europium ions reside in different sites in the BAM lattice [21,23,[30][31][32]. The crystal field acting on the Eu 2+ atoms differs between sites so that the asymmetrical emission spectrum is interpreted as a convolution of the Gaussian-shaped emission spectra of these different sites [21].…”

“…According to Refs. [19,30], the 355 nm light should be absorbed in the mO site, while the 266 nm laser should excite the aBR site.…”

Synthesis of Nanosized Luminescent Materials and Their Photoluminescence under VUV Excitation

“…By Gaussian fitting the VUV emission spectrum, three peaks are found locating at 446nm, 477nm and 517nm, respectively, corresponding to the emission of Eu 2+ in the sites of BR, a-BR and spinel layer. [81][82][83] To probe into the influence of CTAB on VUV emission intensity, the luminescent properties of the nanorods with different concentration of CTAB are depicted under 147 nm excitation. From the inset of Fig.…”
