Realization of Optical Network Structures for Robust Films through Immobilization of Europium Complexes

In this study, the bio-inspired self-cracking substrate can be employed as a template to control the formation of a robust mirco-patterning film. Uniform materials with variable diameters are achieved by optimizing the egg white/water ratios and reaction temperature. The incorporated europium ions exhibit its typical f-f transitions in patterned films. Moreover, the mechanical property and excellent transmittance features have been demonstrated. The current approach can be extended to design two-dimensional nanofabrication of different materials.
