TLDR
In zone refined AgCl, luminescence can be excited by ruby laser light through two-photon processes, while the photoconductivity is a result of ionization of donors as mentioned in this paper.Abstract:
In zone refined AgCl, luminescence can be excited by ruby laser light through two-photon processes, while the photoconductivity is a result of ionization of donors. The luminescence spectrum shows some phonon structure not observed with steady uv excitation.read more

Hole self trapping and recombination luminescence in AgCl at low temperatures
TL;DR: In this article, experimental correlations were established among steady state optical and ESR spectra and transient luminescence and optical absorption, supporting the existence of self-trapped holes in the form of substitutional Ag2+ in AgCl and imply that intrinsic electron-hole recombination is the source of a strong emission band around 2.4 eV.

Luminescence in pure and I-doped AgBr crystals
TL;DR: In this article, the luminescent behavior of pure AgBr and AgBr crystals containing low concentrations (19 /cm 3 ) of iodide ions was investigated in the temperature range 4°K to 80°K.

Some remarks on photoluminescence of AgCl crystals excited by laser or after deformation
TL;DR: In this article, the influence of pressure on AgCl photoluminescence is explained by means of a qualitative model based on charged dislocations for both the elastic and plastic regions of the deformation curve.

Luminescent recombination processes of the self-trapped hole in copper-doped silver chloride
TL;DR: In this article, a new photoluminescence technique was used to study the trapping luminescence of photo-holes in AgCl:Cu 2+, in which both the emission and excitation wavelengths were scanned, to yield a three-dimensional spectrum.

Optical Double-Photon Absorption in CdS
R. Braunstein,N. Ockman +1 more
TL;DR: In this article, the two-photon excitation of an electron from the valence to the conduction band in CdS was observed as a function of laser intensity and compared to the emission excited by single-quanta absorption for photons of the same type.

Mechanism and Defect Responsible for Edge Emission in CdS
TL;DR: In this paper, the authors investigated the nature of green and blue emission at 78°K in CdS and found that the green component has a slower decay with emission occurring as long as 20 μsec after the excitation has ended.
