Optical properties of LFZ grown β-Ga2O3:Eu3+ fibres
Santos, N.F.; Rodrigues, J.; Fernandes, A.J.S.; Alves, L.C.; Alves, E.; Costa, F.M.; Monteiro, T.Due to their relevance for electronic and optoelectronic applications, transparent conductive oxides (TCO) have been extensively studied in the last decades. Among them, monoclinic β-Ga2O3 is well known by its large direct bandgap of ∼4.9 eV being considered a deep UV TCO suitable for operation in short wavelength optoelectronic devices. The wide bandgap of β-Ga2O3 is also appropriate for the incorporation of s...
ZnGa2O4:Mn2+ phosphors grown by Laser Floating Zone
Santos, N.F.; Rodrigues, J.; Nico, C.; Fernandes, A.J.S.; Costa, F.M.; Monteiro, T.Cubic zinc gallate (c-ZnGa2O4) has attracted the attention of the scientific community due to its potential phosphor applications, namely in field emission displays (FEDs) and other electroluminescent devices. Among other advantages, this oxide matrix shows superior thermal and chemical stability when compared to ZnS based phosphors. Most of the above mentioned works comprise nanostructures, thin films or press...

Costa,K.A.P; Assis,R.L; Guimarães,K.C; Severiano,E.C; Assis Neto,J.M; Crunivel,W.S; Garcia,J.F; Santos,N.FThe silage quality of Brachiaria brizantha cultivars ensiled with different levels of millet meal was evaluated. The experimental design was a completely randomized with three replications in a factorial 3 x 4, with three cultivars of Brachiaria brizantha: marandu, xaraés, and piatã and four levels of millet meal 0, 5, 10, and 15%. The addition of millet meal improved the quality of B. brizantha silage. The inc...
