1. Characterization of CBD-CdS Doped with Some Rare Earths III (Eu3+,Ce3+) as Function of Synthesis Time
Rare earths (Europium, cerium)-doped CdS nanofilms are prepared using the growth technique chemical bath deposition (CBD) at the reservoir temperature of 70±2°C varying the synthesis time in a wide range. For the rare earths doped CdS nanofilms the synthesis time was ranged from 80 to 135 min. The rare earths molar concentration was in the range 0.0≤x≤

2. Deposição de A/N por sputtering não reativo
Neste trabalho depositamos via magnetron sputtering de rádio-frequência não reativo nanofilmes de nitreto de alumínio (AlN). Os nanofilmes de nitreto de alumínio são materiais semicondutores com alta condutividade térmica, elevado ponto de fusão, piezoeletricidade e largo "bandgap"(6;2 eV) com estrutura cristalina wurtzítica hexagonal, pertencentes

3. FabricaÃÃo e caracterizaÃÃo elÃtrica de heterojunÃÃes de polianilina-silÃcio para aplicaÃÃo em dosimetria de radiaÃÃo gama
In this work a technique has been developed to fabricate high quality polyanilinesilicon heterojunction diodes for use as gas and/or ionizing radiation sensors. Polyaniline thin films (40 nm thick) produced by spin-coating on silicon substrates, were the active part of the junction structure. The devices presented excellent reproducibility of their electrica

4. SupressÃo seletiva da luminescÃncia de nanofilmes de complexos de lantanÃdeos induzida por radiaÃÃo UV - n-domo: um dosÃmetro molecular
In this work we have developed a new product, a molecular nanofilm, with photonic properties, from which we have developed a dosimetric device for UV radiation, characterized by its unique behaviour, as well as by its selectivity, sensitivity and compactability. The active part of the dosimeter, so called âMolecular Nanodosimetersâ, is composed of a lumine
