Bi3.79Er0.03Yb0.18Ti3–x W x O12 ceramics with different Tungsten (W6+) content (0 ≤ x ≤ 0.10) prepared by solid state reaction method have been investigated. X-ray diffraction (XRD) confirms the formation of single phase material with orthorhombic structure. Both the down conversion (DC) and up-conversion (UC) photoluminescence (PL) of the ceramics under 488 and 980 nm excitation respectively are investigated. Strong green emission at 527, 548 and a weak red emission at 662 nm is seen under an excitation of 488 nm and 980 nm for an optimum W content (x = 0.06) and is attributed to the transitions 2H11/24I15/2, 4S3/24I15/2 and 4F9/24I15/2 respectively The linear dependence of fluorescence intensity ratio (FIR) with pump power density can possibly be used for temperature sensing.
