The imaging efficiency of today's photographic film and paper is influenced in a variety of ways. Among them, the incorporation of dopants is widely used to increase efficiency, control contrast or improve imaging deficiencies such as reciprocity law

Additional information has been obtained on the structure of donor complexes produced by photoelectron trapping at [Cl5 Ir(NMP)]- (NMP = N-methylpyrazinium cation) centres in AgCl microcrystals. Several different [Cl5 Ir(NMP)]- complexes were prepare

Detailed information has been obtained on the structure of pure and aquated complexes in AgCl using multifrequency EPR and powder ENDOR spectroscopy. Because of the anisotropy of the centre g matrix it was possible to selectively excite centres with

Oxygen in oxide form is a common contaminant of BaFBr and BaFCl crystals. Upon x-irradiation of oxide-containing crystals of both materials, ${\mathrm{O}}_{\mathrm{F}}^{\mathrm{\ensuremath{-}}}$ centers are formed, as has been shown previously by ele

Magic-angle-spinning nuclear magnetic resonance (NMR) spectroscopy of BaFBr and BaFCl doped with up to 6 mol.% oxygen (previously enriched to 40% in 17O) has detected sites on which oxygen impurities were incorporated. In BaFBr:O, monatomic O2- is fo

Spatial correlation between the activator ion ${\mathrm{Eu}}^{2+}$ and electron and hole traps generated by x irradiation is thought to play a decisive role in the photostimulated emission process of the storage phosphor BaFBr:${\mathrm{Eu}}^{2+}$. W

An O- centre formed upon hole trapping by O2- in X-irradiated BaFBr is long-lived at room temperature and has been detected by EPR below 30 K. It can also be produced in low concentrations by exposure of BaFBr to sub-bandgap (200-300 nm) radiation. T

The low temperature photoluminescence of sulfide-doped AgBr has been examined with both steady state and pulsed excitation. Emission bands peaking at about 495, 566, 596, and 725 nm are observed, depending upon excitation conditions. Subband-gap exci

ODMR investigations of recombination processes in AgCl have been extended in an effort to reconcile the apparently contradictory interpretations of other workers. The experiments described indicate that for AgCl no single recombination mechanism domi
