Studies from Norwegian University of Science and Technology (NTNU) Reveal New Findings on Nanocrystals (Quantum confinement of PbSe nanocrystals embedded in a spacer ZnSe matrix for solar cell applications)

By a News Reporter-Staff News Editor at Energy Weekly News -- Research findings on Nanocrystals are discussed in a new report. According to news reporting out of Trondheim, Norway, by VerticalNews editors, research stated, "The paper reports quantum confinement of PbSe nanocrystals (NCs) embedded in a ZnSe matrix by rapid thermal annealing of PbSe/ZnSe multiple quantum wells. The distribution of the PbSe NCs within the ZnSe matrix was observed by transmission electron microscopy and the average crystalline size of PbSe NCs was found to be 3-5 nm."

Our news journalists obtained a quote from the research from the Norwegian University of Science and Technology (NTNU), "The cumulative disorder and the absence of long range super-structure order due to quantum well intermixing were inferred from small angle X-ray scattering. The blue shifts in the absorption edge and band edge luminescence emission indicate formation of PbSe NCs."

According to the news editors, the research concluded: "Finally, potential applications in solar cells are discussed."
