White Light Emission From Tb3+/Sm3+ Codoped LiYF4 Single Crystal Excited by UV Light

, 2014
LiYF4 single crystals codoped with Tb3+/Sm3+ ions were synthesized by the vertical Bridgman method. When excited by 374-nm ultraviolet light, the crystals emit violet-blue, blue, green, yellow, orange, and red light.
