Color Tuning from Greenish-Yellow to Orange-Red in Thermal-Stable KBaY(MoO4)3:Dy3+, Eu3+ Phosphors via Energy Transfer for UV W-LEDs

“…Recently, several kinds of host materials comprising molybdates, tungstate, germinate, vanadates, phosphates, ,, titanates, silicate, niobates, and borate ,, have been selected as candidates for rare earth ion doping, in which molybdates are extensively investigated on account of their high chemical and physical stability properties, effective charge transfer (CT) absorption band, low preparation temperature and so forth. In order to acquire a better interpretation on their excellent properties, a large amount of efforts has been devoted to rare earth ion-doped molybdate phosphors. − In 1990, a series of novel KBaRE­(MoO 4 ) 3 (RE = La–Lu, Y, and Sc) were the first reported compounds by Kozhevnikova et al Until 2015, the Nd 3+ -doped laser crystal KBaY­(MoO 4 ) 3 was synthesized via a single crystal growth method by Wang’s group, in which the structural details were analyzed, showing its monoclinic system with space group C 2/ c . This proposes that other rare earth ions could be introduced into this kind of host to produce good luminescence properties based on their similar ionic radii.…”
