| Abstract: |
|
We described the engineering and characterization of photonic colloidal crystals based on silica spheres with incorporated YVO(4):Eu luminescent nanoparticles. These structures exhibit strong angle-dependent luminescent properties. The controlled incorporation of a planar defect in the periodic structures gives rise to the creation of a pass band in the pseudo-gap. In the energy range of this pass band, we observed a strong increase in combination with a sharp width of the emission spectrum, which opens new possibilities for the design of low-threshold and/or single mode photonic crystal lasers. |
