Anti-Stokes luminescence of microcrystals of AgCl0.95I0.05 solid solutions with adsorbed organic dye molecules

We have studied the effect of the characteristic features of aggregation of some organic dye molecules during adsorption on the parameters of low-temperature sensitized anti-Stokes luminescence (SASL) in microcrystals of AgCl_0.95I_0.05 solid solutions. We have demonstrated the possibility in principle of varying the position of the maximum in the SASL excitation spectrum and its intensity by varying the concentration of the dye molecules deposited on the surface of the AgCl_0.95I_0.05 microcrystals. We have observed that the intensity of SASL excitation for these samples increases as different types of dye aggregates form on their surface. __________ Translated from Zhurnal Prikladnoi Spektroskopii, Vol. 73, No. 5, pp. 592–596, September–October, 2006.
