• Synthesis and characterization of Dy-doped Lu$_1$Gd$_2$Ga$_2$Al$_3$O$_{12}$ phosphor for LEDs

The synthesis and characterization of Dy-doped Lu$_1$Gd$_2$Ga$_2$Al$_3$O$_{12}$ are reported in this article. Solid-statereaction method is used to synthesize the material. X-ray diffraction and scanning electron microscopy characterization techniques are used to study the phase and structure of the synthesized material. Luminescence, which is the main propertyof the phosphor material, is characterized by UV- and X-ray-induced luminescence spectroscopy. Lu$_1$Gd$_2$Ga$_2$Al$_3$O$_{12}$:Dy$^{3+}$phosphor shows its highest emission spectra in blue and yellow regions. A combination of yellow and blue gives us white light, displayed by chromaticity diagram for this phosphor. Hence, this phosphor may be used in white-light-emitting diodes. The absorption spectra of our material match well with spectral curve of LEDs. Therefore, it may be used in LEDs applications.
