Environmentally benign luminescent quantum dots--challenges and opportunities.
Luminescent semiconductor quantum dots (QD) have attracted the attention of the science and engineering communities due to their unique photo-physical and chemical properties, which enable their use in a broad range of technological applications ranging from luminescence biomedical imaging to consumer electronic devices like TVs, cell phone and tablet screens. The chemical composition of first generation luminescent QD, which often contain toxic elements like cadmium and lead, and their chemical degradation in the environment have raised significant environmental and health concerns about their use, particularly in widely used consumer electronic products. The presentation will describe the fundamental principles and state of the art of first generation luminescent QD, and recent advances towards the synthesis and application of benign by design QD that retain their function while minimally impact human health and the environment.
Zeev Rosenzweig obtained his PhD degree in Physical Chemistry from the Hebrew University of Jerusalem in 1992. In 1995, following three years of postdoctoral training at Iowa State University and the University of Michigan, he assumed a faculty position in the Chemistry department of the University of New Orleans where he developed a research program in nanosensors. He quickly rose through the academic ranks and became a Full Professor in 2001. In 2005, in the aftermath of Hurricane Katrina, Dr Rosenzweig joined the National Science Foundation as a Program Director in the Chemistry Division and served the community in this role until 2014. He then assumed the position of Professor and Chair of the Department of Chemistry and Biochemistry at the University of Maryland Baltimore County where he developed a new research program in nanoscience, with a strong focus on developing environmentally benign nanoparticles. Dr Rosenzweig has published over 100 research articles and book chapters pertaining to his research and has mentored 25 graduate students and postdocs during his career.
