Preparation of Bitter Melon-like Ordered Porous Fluorinated Eu3+-Phenanthroline/ZnO Composite with Yellow Light Emission
The soft template method was used to synthesize the ordered porous ZnO precursor and with 1,10-phenanthroline as an organic ligand, Eu3+ as a luminescent center ion, and NH4F as a fluorine source, a kind of much uniform bitter melon-like ordered porous fluorinated Eu3+-phenanthroline/ZnO composite w...

Zusammenfassung: | The soft template method was used to synthesize the ordered porous ZnO precursor and with 1,10-phenanthroline as an organic ligand, Eu3+ as a luminescent center ion, and NH4F as a fluorine source, a kind of much uniform bitter melon-like ordered porous fluorinated Eu3+-phenanthroline/ZnO composite was finally prepared through the hydrothermal method. The average length of the bitter melon-like particles was 0.7-1.0 μm, and its average diameter was 300-400 nm, which had a lot of ordered mesoporous dispersed on the surfaces. The prepared materials showed strong yellow and blue light emission under 394 and 275 nm excitation, respectively. The optimum synthesized conditions were determined according to the synthesis parameter of the sample with the strongest emission peak intensity |
