Investigation on luminescence characteristics of Dy-Tb co-doped phospho-tellurite glasses for tunable green/ white LED applications.

Dy/Tb co-doped glasses have drawn profound attention for their potential in solid state lighting due to their unique luminescence properties. This research highlights the effect of compositional variation on structural and optical characteristics of Dy/Tb co-doped phospho-tellurite glasses through a comprehensive analysis involving X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR) and photoluminescence (PL) studies. XRD and FTIR spectroscopy are conducted to characterize the glass matrix and confirm its structural integrity.
