Abstract
The enhancement in luminescence efficiency and spectral tuning due to Y3+ incorporation in the SrGd1.94Eu0.06O4 phosphor is reported. An auto-combustion method was adopted to synthesize the samples. The structural, morphological and luminescence properties were examined by means of X-ray diffraction, field-emission scanning electron microscopy (FESEM) and photoluminescence (PL) studies. The substitution of Gd3+ ions by Y3+ ions modulates the sensitizing effects of Gd3+ ions and also causes lattice shrinkage which alters the local crystal structure and improves the red light yield of Eu3+ ions. The spectroscopic modification occurring due to the incorporation of Y3+ ions was investigated with the help of Judd-Ofelt calculations. Temperature dependent PL studies were performed to investigate the thermal stability of the samples. The present research indicates that the SrGd1.94-xYxEu0.06O4 system can be used as a suitable red component for display and lighting applications.
