"Exciplex tuning" by varying the dopant concentration

Article Abstract:

A study was conducted to analyze the dependence of the dicyanoargentate(I) luminescence on the dopant concentration in (Ag(CN)(sub 2)-)/KCL single crystals. The crystals were prepared by slowly evaporating at ambient temperature aqueous solutions supporting KCl and KAg. Results indicated that the excitation energy is transferred between different oligomers and leads to the tunable emission observed in the system.

"Write/read/erase" with laser irradiation of dicyanoargentate(I) doped and pure crystals

Article Abstract:

The effect of laser irradiation and temperature on the luminescence properties of three dicyanoargentate(I) doped and pure crystals are described and the results are analyzed to show the effect of varying the Ag content on the rate of the "write/read/erase" process. It concluded that the changes observed are progressive with increased irradiation time, and they are also reversible.

Luminescence thermochromism in dicyanoargentate (I) ions doped in alkali halide crystals

Article Abstract:

A study of the temperature-dependent photoluminescence properties of single crystals of alkali halides doped with dicyanoargentate (I) ions is discussed. The luminescence spectra are strongly affected by controlling the temperature, excitation wavelength and changing the alkali halide host crystal from KCl to NaCl.
