Peapodlike heterostructure composed of particles orderly embedded in the high-crystalline nanoribbons was fabricated via a two-step thermal reaction route. The room temperature photoluminescencespectrum of the products showed a strong and stable blue emission centered at 467 nm under excitation at 320 nm, which was attributed to the especial heterostructure. This technique also provided a general and convenient approach for preparing even more complex heterostructures and would be useful in improving the properties of materials.
