Abstract:

The precise control of phosphors with well-defined features remains a challenging issue since its property has been closely related to the shape, surface modification and particle size. The studies to develop microstructure under mild conditions will be of general interests. Herein, 2-thenoyltrifluoroacetone (TTA) has been incorporated as a viable technique to bind with surface of BaMgF₄:Eu³⁺ phosphor and such process has been proved to be an effective strategy in preparing inorganic materials. The well acceptable advantages of this way include facile synthesis steps, broaden excitation range and reduced particle size. Although lanthanide fluorides have been reported so far, there are limited studies concerning organic framework appended red phosphors. In this way, the exploitation of a simple method to assemble hybrid phosphors will be very valuable in opto-electronic industries.
