摘要

In this article, a series of Al3+ ion incorporated Y2WO6:xNd3+ (where, x = 0.5–5 mol %) synthesized using citrate assisted sol–gel technique. The formation of host lattices as monoclinic crystal structure is confirmed by XRD. The higher amount of Al3+ in Y2WO6 host lattice leading to Y0.5Al1.5WO6 indicative of an admixed phase resulting in distortion in monoclinic structure. The colloidal structured morphology along with presence of an individual element is revealed by SEM and EDS analysis. Band gap of Y2WO6 lattices is estimated as 3.86 eV, gradually decreases due to addition of Al3+ ion and different trend in noted when doped with Nd3+ ion. The characteristic Nd3+ PL emission with maximum intensity is noted at ≈1070 nm (4F3/2 → 4I11/2) in the NIR region under the 885 nm (4I9/2 → 4F3/2) excitation in the phosphor. The position of prominent emission peaks remains intact regardless of alteration in Al3+ content. Inadequate literature has been reported on Y2WO6:Nd3+ phosphor. However, effect of Al3+ ion on photoluminescence properties is unacquainted leading to a new Y2–xAlxWO6:Nd3+ phosphor has potential for optoelectronic applications in NIR region.
