Structural and Optical Characterization of Luminescent (Y0.7Gd0.3)2O3:Eu Nanopowder and Translucent Ceramics
Phosphor nanomaterials are of special interest today due to their broad range of applications from the solid state lightening and novel flat displays to high resolution X-ray detectors and sensors in biomedicine. Among them polycrystalline Eu 3+ doped mixed oxide (Y 1-x Gd x) 2 O 3 is a well-known luminescent material widely used to provide red light emission for modern optoelectronic devices [...
متن کاملSol-gel synthesis and characterization of alumina-15%mullite composite nanopowder
Homogeneous distribution of mullite in the matrix of alumina can be obtained through sol-gel method. In this work, nanopowder of alumina-mullite composite was synthesized with high homogeneity and high purity. So aluminum chloride hexahydrate and tetraethyl orthosilicate were used instead of alumina or mullite nanopowder. Studying the simultaneouse thermal analysis (STA) of mullite precursor re...
متن کاملMullite-alumina functionally gradient ceramics
Cracks free mullite-alumina Functionally Gradient Ceramics (FGC) have been obtained by sequential slip casting of Mullite-alumina slurries with diserent mullite/alumina ratios. These slurries were prepared with 65 % solids content and viscosities rangingpom 10 to 40 mPa.s. 7he presence of cracks perpendicular to the FGC layers have been attributed to residual stresses developed because of the m...
متن کاملSurface Contamination of Alumina Ceramics by Carbon
Article history: Received: 01.05.2016. Received in revised form: 25.07.2016. Accepted: 06.09.2016. This study presents the results of investigating the cause of contamination of aluminum oxide ceramics (Al2O3) in the form of brown colored stain. Contaminated ceramic surfaces were examined with the scanning electron microscope (SEM) equipped with the Energy Dispersive Spectrometer (EDS). The res...
