Photoluminescent properties of Sm3+ and Tb3+ codoped CaWO4 nanoparticles obtained by a one‐step sonochemical method

Luminescent materials with LED applications can have your emission color controlled by rare earth doping. In this work, Sm3+- and Tb3+-codoped CaWO4 nanoparticles were obtained by a one-step sonochemical method. The nanoparticles were characterized by X-ray difractogram (XRD), Raman scattering (RS)...
