Luminescent thin films of hybrid silica-based materials were studied and an Eu-containing one was coated on a near-UV LED chip to be investigated as a red phosphor.
Mn4+-activated oxidefluoride phosphors are attractive for application in wide solid-state lighting devices because of its distinct red emission at about 630 nm and the abundant storage of Mn4+ ion. However,...
A new red phosphor Cs2TiF6:Mn4+has been prepared by a facile cation exchange route, which can absorb the broad blue band and emit intense red light efficiently, and can be a potential candidate for application in indoor lighting WLEDs.
