“…has been reported in the literature that the ratio R of the integrated intensities 5 D 0 A 7 F 2 over 5 D 0 A 7 F 1 is indicative of the asymmetry of the coordination polyhedron of the Eu 3+ ion. 40,41 R is 2.7 for the reference C1 and 5.3 for the ZnO/Eu 3+ -dcbpy film. Therefore the local environment in the hybrid film is more distorted than in the free Eu 3+ -dcbpy complex.…”

“…Classically, glass samples prepared by the sol−gel process are composed of silica (SiO 2 ). Replacement of the silicon alkoxide precursors by other easily hydrolyzable metal alkoxides will allow one to obtain other types of lanthanide-doped oxide materials like alumina (Al 2 O 3 ), titania (TiO 2 ), zirconia (ZrO 2 ), ,,,,, hafnia (HfO 2 ), ,, tantalum(V) oxide (Ta 2 O 5 ) , or germania (GeO 2 ) . In general, these metal and transition-metal alkoxides are more reactive toward hydrolysis and condensation reactions than the silicon alkoxides.…”

“…Este termo denota a absorção da radiação ultravioleta pelos ligantes, a transferência de energia do estado excitado do ligante para o íon lantanídeo e a emissão da radiação na região visível característica de cada íon. 8 Os íons lantanídeos isolados possuem pequena absortividade molar (ε), por este motivo, são coordenados a ligantes orgânicos que, por possuírem maiores valores de ε, atuam como sensibilizadores (também chamados de "antenas"), aumentando assim a eficiência da luminescência. 9 Visando ao aprimoramento constante do serviço prestado pelas perícias, o presente estudo teve como propósito investigar a propriedade luminescente do material híbrido orgânico-inorgânico sintetizado, bem como avaliar sua capacidade de revelar impressões digitais latentes.…”
