The Zhang research group is primarily interested in the design,
development, characterization, and application of
advanced materials with emphasis on optical and
electronic nanomaterials (nanocrystals or quantom dots)
of both semiconductors and metals.
These nanomaterials have novel physical and chemical properties
due to quantum confinement and exceedingly large surface to volume
ratio. The design and synthesis of the materials are
mostly based on inorganic colloidal chemistry methods. The
synthesized materials are characterized systematically and
extensively using a variety of experimental techniques including
SERS (surface-enhanced Raman scattering), optical spectroscopy, ultrafast laser,
x-ray (XAFS, XPS), ESR, electrochemical, and microscopy. In the meantime, the group
actively explores emerging technological applications of
these advanced nanomaterials in areas such as solar energy
conversion, hydrogen generation and storage, cancer
biomarker detection, photocatalysis, sensors, imaging, detectors, and lasers.
A number of projects have been accomplished and several are currently under
investigation. Some examples of on-going projects include:
1. Surface-enhanced Raman scattering (SERS) based on Au and Ag
nanoparticles/aggregates and development of SERS sensors for
chemical and biomedical detection with emphasis on cancer biomarkers
including antigens and antibodies of ovarian and lung cancers.
2. Ultrafast interfacial electron dynamics and surface modification of
semiconductor nanoparticles: CdS, CdSe, CdTe, PbS, Ag2S, CuS. Biocnjugation
of semiconductor quantum dots to proteins for biomedical detection based on
photoluminescence
3. Hydrogen generation and storage based on novel semiconductor, oxide,
and metal nanostructures including nanowires and nanorods via photoelectrochemistry or photocatalysis.
4. Photoluminescence and up-conversion luminescence of doped
semiconductor nanoparticles: Mn2+ in Mn2+-doped ZnS,
ZnSe, CdS nanoparticles
5. Solar energy conversion based on dye, polymer, or quantum dot sensitized
nanocrystalline TiO2 solar cells using
conjugated polymers as solid electrolytes
6. Hot electron relaxation in metal nanoparticles and nanoparticle aggregates: Ag, Au, Pd, and Pt
7. Photothermal imaging and therapy of cancer cells using hollow gold
nanoshells (HGNs)
