Significant enhancement of blue photoluminescence intensity of Dy3+ modified Sr6Ca4(PO4)6F2:Eu2+ phosphors

Cation vacancy-boosted BaZnB4O8:xEu3+ phosphors with high quantum yield and thermal stability for pc-WLEDs

“…12,13 The remaining methods involve combining blue or near-UV LED chips with red, green and blue phosphors. [14][15][16][17] Currently, the third method has been considered to be the most effective and convenient method to obtain pc-WLEDs. The commercial tricolor phosphors include red (Y 2 O 2 S:Eu 3+ ), green ((Ba,Sr) 2 SiO 4 :Eu 2+ ) and blue (BaMgAl 10 O 17 :Eu 2+ ) phosphors.…”

Designing a Polyphosphate Polymorph of CsMg(PO3)3 as Host Lattice for Preparing Single Mn2+-Oxidation Doped Phosphor in the Open Environment

“…Research on developing new phosphors has never been interrupted over the past 50 years. − In a majority of the cases, a phosphor is composed of a host material and an activated ion. The most famous activators are Eu 2+ and Ce 3+ , which produce a large number of excellent phosphors. − As a nonrare-earth element, manganese is cheaper than a rare-earth element and it also has a possibility to realize high photoluminescence quantum yields for convenient applications. , Generally, manganese has two major oxidation states of +2 and +4 and can dope into different types of host materials to form multiple types of phosphors. For example, Chen et al prepared K 2 TiF 6 :Mn 4+ phosphor by efficient cation exchange reaction method to realize a high quantum yield of 98% .…”
