High-quality reddish-orange-emitting Sr6Y2Al4O15:Eu3+ phosphors for solid-state lighting and anti-counterfeiting applications

Rare-Earth-Ion (RE3+)-Doped Aluminum and Lanthanum Borates for Mobile-Phone-Interrogated Luminescent Markers

“…The applications of Eu-doped La and Al borates are diverse due to their unique excitation-emission spectra [6,7]. These include uses in anti-counterfeiting [8,9] and potential applications in plasma displays [10]. In all of the above and in other applications, it is of crucial importance to be able to detect, identify, and track such luminescent markers remotely using worldwide available smartphones [11][12][13][14][15][16], which are more affordable than professional spectrometers and are compatible with Internet of Things technology, thus allowing intelligent sensing networks to be developed.…”
