Two novel hierarchical architectures, flower-like and urchin-like MgBO2(OH), were facilely fabricated through a hydrothermal process, in the absence of any surfactant or template. Mg3B2O6 can be obtained by thermal decomposition of the MgBO2(OH) precursor with the morphology well-retained. These unique Mg3B2O6 assemblies were composed of uniform nanosheets and nanobelts, respectively. Under UV excitation, Eu3+-doped Mg3B2O6 shows a strong red emission corresponding to 5D0 → 7FJ (J = 1,2,3) transition of Eu3+. Interestingly, variable architectures of Mg3B2O6:Eu3+ from flower-like to urchin-like displayed tunable emission from 592 nm (5D0 → 7F1) to 611 nm (5D0 → 7F2) through the altering of symmetry of the crystal field around Eu3+ ions. The present architectures are envisaged to be potential candidates for fluorescent lamps and field emission displays.
