Computer simulation of photoconductivity decay in AgBr microcrystals: Relaxation model
Hailstone, Richard; Erdtmann, David (American Institute of Physics, 1994-10-01)Previous workers have explained photoconductivity decay in AgBr microcrystals by proposing a model involving lattice relaxation following shallow surface trapping of electrons. This model is investigated using Monte Carlo ... -
A computer simulation study of silver-gold cluster formation on AgBr tabular microcrystals with AgIBr cores
Hailstone, Richard; DeKeyzer, Rene (American Chemical Society (ACS), 2001-08-09)Computer simulation is used to study how an iodobromide core in an AgBr tabular microcrystal affects the efficiency of photoinduced metal cluster formation. Iodide ions can trap photogenerated holes and act as recombination ... -
Effect of I– impurity on the efficiency of silver cluster formation on AgBr microcrystal surfaces
Hailstone, Richard (American Institute of Physics, 1999-08-01)Computer simulation is used to study the effect of iodide impurity on silver cluster formation on AgBr microcrystals. The simulation is based on a nucleation-and-growth model of silver cluster formation in competition with ... -
Luminescent colloidal silicon nanocrystals prepared by nanoseconds laser fragmentation and laser ablation in water
Svrcek, Vladimir; Mariotti, Davide; Hailstone, Richard; Fujiwara, Hiroyuki; Kondo, Michio (Materials Reseach Society (MRS), 2008-03)The surface states of silicon nanocrystals (Si-ncs) considerably affect quantum confinement effects and may determinate final nanocrystals properties. Colloidally dispersed Si-ncs offer larger freedom for surface modification ... -
Photography: Making every photon count
Hailstone, Richard (Nature Publishing Group, 1999-12-23)More than 150 years after the invention of photography, the underlying solid-state photochemistry is still being investigated and improved. One aspect of continual importance is the efficiency of the image-recording stage, ... -
Selenide versus sulfide centers on (100) AgIBr surfaces: characterization and energy levels
Hailstone, Richard; French, J.; DeKeyzer, Rene (Maney Publishing on behalf of the Royal Photographic Society, 2003)Sensitometric and spectroscopic techniques are used to characterize sensitizer centers produced by sulfur and selenium sensitization of AgIBr cubes. Sulfur sensitization primarily affects the long-wavelength sensitivity ...
