Annotation Novel red-emitting SrGd2(1 – x)Eu2xO4 samples were prepared via combustion method. Structural and optical characteristics were examined with the help of XRD, FTIR, FESEM and photoluminescence (PL) studies. FESEM images reveal agglomerated rod-like morphology. The intense red emission corresponding to 5D0→7F2 transitions under UV-excitation 276 nm and higher thermal stability up to 250 °C of SrGd2(1 – x)Eu2xO4 reveals its applicability in lighting and display devices.
