What is it about?

Dy3+‐doped CaAl12O19 phosphors were synthesized utilizing a combustion method. Crystal structure and morphological examinations were performed respectively using X‐ray diffraction (XRD) and scanning electron microscopy (SEM) techniques to identify the phase and morphology of the synthesized samples.

Why is it important?

At the present time, the development of energy‐saving lighting is an essential core interest for researchers. Large amounts of power can be saved by using efficient energy‐saving light sources. Traditional incandescent and fluorescent lamps, with their resulting heat or gas release, have related colossal energy losses.[

Perspectives

Using urea as the fuel, combustion method was used to synthesize a white light‐emitting CaAl12O19:Dy3+ phosphor. The resulting phosphor had a hexagonal crystal structure. Substitution by Dy3+ ions at the cationic sites of Ca2+ was confirmed by structure analysis.
