Aktuelle Entwicklungen auf dem Gebiet der anorganischen Leuchtstoffe

Abstract: Energiesparen ist angesagt! Eine Steigerung der Energieffizienz ermöglichen neue anorganische lumineszierende Materialien, wie sie in Displays und weißen Leuchtdioden (Bild: Farbdiagramm; Mischung der drei Emissionen A–C liefert beliebige Farbtöne innerhalb des Dreiecks) zum Einsatz kommen. In Hg‐freien Leuchtstoffröhren könnten sie einen Beitrag zum Umweltschutz leisten; außerdem liefern sie bessere Szintillatoren für die medizinische Diagnose.magnified imageAngesichts knapp werdender Rohstoffe und des zu erw… Show more

“…Synthesis: Oxonitridophosphates can be synthesized from multicomponent reactant systems that consist of metal salts (e.g., halides, sulfides) and P/(O)/N-containing molecules, usually phosphoryl triamide OPA C H T U N G T R E N N U N G (NH 2 ) 3 and thiophosphoryl triamide SPA C H T U N G T R E N N U N G (NH 2 ) 3 . [20,21] At approximately 750 8C, the latter act as P/N and P/O/N sources, respectively [Eqs.…”

“…Dieser Aufsatz gibt nur einen kurzen Überblick über einige der vielversprechendsten Leuchtstoffe. Ausführlichere Übersichten zur Lumineszenz von (Oxo)nitridosilicaten wurden durch Hçppe, [188] Xie, [94] Setlur, [189] He [190] [176] und van Krevel. [192] Seither sind die Lumineszenzund Materialeigenschaften der 2-5-8-Familie und ihrer Mischkristalle vielfach untersucht worden.…”

“…The structural diversity of oxosilicates is limited to terminal or singly bridging O atoms, whereas N atoms in nitridophosphates may occur as N [1] , N [2] , N [3] , or even N [4] atoms. [19,20] In this case, for example, green (e.g. Furthermore, nitridic zeolites promise useful chemical and physical properties (for example, adjustable acidity/basicity).…”
