Abstract
The present research article explains the upconversion emission behaviour of Ho3+-Yb3+ codoped XWO4 (X = Ba, Ca, Sr) phosphors synthesized using a solid-state reaction technique. The phase formation and structural study were confirmed through X-ray diffraction and Scanning electron microscopy analysis. The role of different host matrix on the upconversion emission spectra have been recorded by 980 nm excitation. The comparison of upconversion emission of Ho3+-Yb3+ codoped XWO4 (X = Ba, Ca, Sr) phosphors was studied. A two-photon absorption process is proposed to achieve the observed upconversion emission via a suitable energy level structure.
