Red/blue-shift dual-directional regulation of α-(Ca, Sr)2SiO4:Eu(2+) phosphors resulting from the incorporation content of Eu(2+)/Sr(2+) ions

摘要: In this work, tunable emission from green to red and the inverse tuning in α-(Ca, Sr)2SiO4:Eu(2+) phosphors were demonstrated magically by varying incorporation content of Eu(2+) Sr(2+) ions, respectively. The properties mechanism red-shift resulting as well that blue-shift induced investigated detail. As a result fine-controlling Eu(2+), peak red-shifts 541 nm 640 nm. On other hand, inversely blue-shifts 546 through fine-adjusting Sr(2+). excellent characteristics for presented work exhibited their various application prospects solid-state lighting combining with blue chip or near-UV chip.
