• spectra for all samples. It is positioned at 394 nm and corresponds to the 7F0→5L6 transition in Eu3+. As far as absorption and excitation of Eu3+ ions are concerned, it is the most probable and most frequently observed transition according to literature [23][42][43]. Samples deposited on Au plasmonic

• platforms show an increased intensity of the excitation peak. Moreover, samples with an additional aluminium oxide ultrathin film exhibit a higher excitation intensity. The increased excitation for samples with Au nanostructures may be ascribed to the plasmonic resonance effect, which results in greater
