Abstract: Experimental and computational studies of photophysical processes in silver halide imaging materials are presented. Recent investigations that have refined our understanding of carrier recombination paths, exciton behavior, quantum confinement effects, and the structure and function of small surface silver clusters are detailed. The theory and mechanism of electron and hole injection from photoexcited surface-adsorbed dye molecules are outlined. The carrier trapping properties and subsequent photophysics of transition-metal dopant complexes are presented. Particular emphasis is given to the role of relaxation processes in electron and hole trapping events.

The role of effective mass of carrier in the photocatalytic behavior of silver halide-based Ag@AgX (X=Cl, Br, I): a theoretical study.
TL;DR: The crystal field splitting of the Ag 4d bands in the valance band of silver halides is found to be a main factor leading to the large effective mass of the photogenerated holes and consequently to a weaker transfer ability, and a new crystal design and exerting strain along the coordinate axis are proposed as solutions to decrease the effectivemass of holes.

Mechanism of Agn nanocluster photoproduction from silver oxide films
TL;DR: In this paper, the effects of external conditions on written nanocluster fluorescence are interpreted in terms of a mechanistic understanding of fluorescent Agn nanoclusters creation and subsequent spectral dynamics, illustrating the equilibrium between nancluster creation and destruction.

Development of the Colle-Salvetti correlation-energy formula into a functional of the electron density
TL;DR: Numerical calculations on a number of atoms, positive ions, and molecules, of both open- and closed-shell type, show that density-functional formulas for the correlation energy and correlation potential give correlation energies within a few percent.

Density-functional exchange-energy approximation with correct asymptotic behavior.
TL;DR: This work reports a gradient-corrected exchange-energy functional, containing only one parameter, that fits the exact Hartree-Fock exchange energies of a wide variety of atomic systems with remarkable accuracy, surpassing the performance of previous functionals containing two parameters or more.
