Calcium Silicate Nanophosphors for White LED and Display Applications:Silicate based phosphors due to stable crystal structure, high thermal stability, low thermal conductivity, resistance to acids and alkali they were being used in light industry. Among the various silicates, strontium orthosilicate and magnesium silicates showed applications in the fields of sensors, field emission displays (FEDs), compact fluorescent lamps (CFLs), white light emitting diodes (WLEDs), and plasma display panels (PDPs), etc. It was well known that the luminescent properties of inorganic nano/micro materials...

Currently, biological methods compared with conventional chemical and physical methods, could be a preferable synthesis route due to environmentally friendly conditions, despite their lower speed of metal reduction, it does not require further stabilizing agents, because extracts themselves act as stabilizing and capping agents and the nano powders, prepared by biological methods, rendering a good antimicrobial activity. Rare earth (RE) doped lanthanum oxyfluorides (LaOF) have been widely used in high performance luminescent devices, magnets, catalysts and other functional materials based on...

Dans le domaine de la science et de la technologie, les faisceaux d'ions continuent d'offrir de nouvelles possibilités en matière de caractérisation et d'analyse des échantillons, de développement de matériaux, de modification des propriétés sélectives, etc. Les méthodes de faisceau d'ions fournissent un ensemble d'outils hautement contrôlables qui peuvent être utilisés pour une investigation systématique au niveau atomique et finalement contrôlés et exploités au niveau macroscopique. Ici, nous avons fait un effort pour étudier les propriétés de luminescence...

Ionenstrahlen bieten in Wissenschaft und Technik immer neue Möglichkeiten für die Charakterisierung von Proben, die Analyse, die Entwicklung von Materialien, die Veränderung selektiver Eigenschaften usw. Ionenstrahl-Methoden bieten ein hochgradig kontrollierbares Instrumentarium, das für die systematische Untersuchung auf atomarer Ebene eingesetzt und schließlich auf makroskopischer Ebene kontrolliert und genutzt werden kann. Hier haben wir uns bemüht, die Lumineszenzeigenschaften (Ionolumineszenz, Photolumineszenz und Thermolumineszenz) von ionenstrahlinduzierten, mit seltenen Erden...
