Abstract:A series of Er3+ ions doped Sr9Y2W4O24 (SYW) phosphors have been synthesised using solid‐state reaction technique. For optical thermometry and solid state lighting applications, the crystal structure, morphological, and luminescence features of the SYW: Er3+ phosphors were explored. X‐ray diffraction (XRD) reveal that synthesised phosphors having single phase with a tetragonal crystal structure and I41/a space group. SEM was used to examine the morphological behaviour and presence of composition elements. The … Show more
