Morphology Evolution and Luminescence Properties of YF₃: Sm Nano-/Microcrystals

Abstract:

Abstract. Recently, there has been increasting interest in the doping of nano-/microcrystal hosts with Sm³⁺. However, very few examples of Sm³⁺ doped YF₃ -based nanophosphors have been reported. In this paper, a variety of uniform YF₃:Sm nano-/microcrystals have been successfully prepared by a facile, effective, and environmentally friendly hydrothermal method. The morphology evolution process has been investigated by quenching the reaction at different time. Based on the results, a possible growth mechanism is presented in detail. The as-obtained YF₃:Sm nano-/microcrystals show strong yellow and red light emissions under room temperature, which is quite different from those reported previously and might find potential applications in fields such as light phosphor powers and advanced flat panel display devices.
