“…Due to these potential technological applications, terbium is a valuable activator and the understanding of its role and optical properties is of great importance. A large number of studies have been lately dedicated to terbium ions doped oxide-based matrices such as yttrium/gadolinium aluminate [4][5][6][7], gadolinium tungstate [8] or lutetium tantalate [9].…”

“…As de menor resolução cobrem intervalos espectrais maiores e podem ser utilizadas para uma primeira análise do espectro de cintilação. Além disso, materiais diferentes possuem emissões em regiões diferentes do espectro, muitas vezes com espaçamento entre as bandas de mais de 300 nm, como nos casos de compostos dopados com Pr 3+ e Tb 3+ , [18][19][20] 25 visando sua aplicação em tomografia de emissão de pósitron. Aqui o material se apresenta na forma de pó, constituído por partículas em torno de 50-100 nm de diâmetro.…”

“…Detalhes sobre a preparação e a caracterização estrutural desse material, além das propriedades de luminescência com excitação por UV podem ser obtidas em Oliveira et al. 18 O material foi submetido aos raios X de Cu (1-20 keV) gerados no difratômetro variando-se a potência nominal de entrada no tubo na faixa de 100-700 W. Os espectros de emissão…”

“…Other investigations on the luminescence properties of lanthanide-based systems with NPs, nanorods or systems assembled using sol-gel techniques have been reported in the literature [17,22,27,33,34,38,40,43,45,49,50,60,61,67,73,78,82,88,93,107,[127][128][129]133,136,140,142,143,149,163,[169][170][171]176,178,201,211,212,214,[235][236][237][238][239][240][241][242][243][244][245]…”
