摘要：
Core/shell Y(OH)CO3:Eu3+/YBO3:Eu3+ composites with a well-defined spherical shape and narrow size distribution were fabricated through a simple hydrothermal process for the first time. Y(OH)CO3:Eu3+/YBO3:Eu3+ composites can be obtained via Y(OH)CO3:Eu3+ colloidal spheres partly reacted with H3BO3, with the morphology well-retained. Under UV excitation, the core/shell Y(OH)CO3:Eu3+/YBO3:Eu3+ phosphor emits the typical orange-colour light originating from the D-5(0) -> F-7(J) transitions of the YBO3:Eu3+ shell. The spherical particles might have potential application for high resolution screens, displays and flat panels.
