Photoluminescence properties of Al3GdB4O12:Eu phosphors

An investigation is reported of the photoluminescence (PL) properties of Al3GdB4O12:Eu phosphors. Under vacuum ultraviolet excitation, Al3GdB4O12:Eu exhibited a bright red luminescence with CIE chromaticity coordinates of (0.643, 0.356) with a PL intensity of 60% of the sodium salicylate standard. The PL spectrum showed a ground state splitting pattern consistent with D3 symmetry. The PL excita...

High Speed Preparation of GdCaAl3O7:Eu Nano-Phosphors by Microwave-Assisted Combustion Approach

GdCaAl3O7:Eu red nano-phosphors were synthesized by solution combustion using urea as fuel. Fourier-transform infrared, X-ray diffraction, scanning electron microscope, transmission electron microscope and photoluminescence spectrophotometer were used to characterize the obtained samples. XRD patterns revealed that GdCaAl3O7:Eu pure phase was formed by combustion of metal nitrate solution in th...
