Enhanced novel orange red emission in LiSr4−x (BO3)3:xSm3+ by K+
Source abstract
Abstract
LiSr4−x(BO3)3:xSm3+ and LiSr3.985−x(BO3)3:0.015Sm3+, xK+ phosphors were prepared by solid-state reactions. The phases and luminescent properties of the obtained phosphors were characterized. The results demonstrate that the phosphors particles emit an intensive reddish orange light emission under excitation at 403 nm. LiSr4−x(BO3)3:xSm3+ phosphor can be efficiently excited by ultraviolet and blue light, and the emission spectrum consists of three emission peaks at 564, 601 and 647 nm. The introduction of the charge compensator K+ into the LiSr4−x(BO3)3:xSm3+ phosphor matrix promotes the increase of the emission intensity, as well as the decrease of the Eg value. Results suggest that LiSr3.97(BO3)3:0.015Sm3+, 0.015 K+ is a promising orange–red emitting phosphor for UV LED applications.
