New Findings in Materials Science Described from Hunan University (Microphotoluminescence of individual ZnSe nanoribbons)

August 12, 2014

By a News Reporter-Staff News Editor at Journal of Technology -- A new study on Materials Science is now available. According to news reporting originating from Changsha, People's Republic of China, by VerticalNews correspondents, research stated, "ZnSe nanoribbons were synthesized and characterized with microphotoluminescence (mu-PL) spectra and mappings. The mu-PL results show that the near band edge (BE) and the deep defect (DD) level related emissions are predominantly located at the central and the edge region of the ribbons, respectively."

Our news editors obtained a quote from the research from Hunan University, "Combining with the HRTEM, the DD related emission is attributed to the structure defects mainly located at the edge of the ribbon. It is found that the DD related emission consists of three bands, centered at 635, 560 and 535 nm, respectively. The temperature dependent PL spectra further demonstrate that the carriers transfer among the different defect states through the thermally activated mechanism."

According to the news editors, the research concluded: "The results provide more direct evidence about the origin of trap state related emissions in ZnSe nanostructures."
