title: Composite Yttrium-Carbonaceous Spheres Templated Multi-Shell YVO4Hollow Spheres with Superior Upconversion Photoluminescence.
abstract: Complex oxide YVO4multi-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:Yb3+/Er3+hollow spheres might be attributed to the enhanced near-infrared excitation light harvesting efficiency originated from the multiple reflections.
