Abstract

Abstract : Complex oxide YVO4 multi‐shell hollow spheres with uniform morphologies and controllable shell numbers are successfully prepared by using a newly developed and general composite yttrium‐carbonaceous sphere templated approach. The prominent upconversion luminous intensity of the YVO4 :Yb 3+ /Er 3+ hollow spheres might be attributed to the enhanced near‐infrared excitation light harvesting efficiency originated from the multiple reflections.
