โœฆ Synopsis


A method for incorporating quantized particles of colloidal semiconductors in transparent silicate glasses has been developed.

The absorption spectra of the particles in the glasses are identical to those of the starting colloidal aqueous solutions. The luminesccnce intensity of colloidal semiconductors in silicate glasses is much higher than that for colloids in liquid solutions. This is attributed to passivation of surface recombination sites by the silicate polymer.

Three types of sol-gel processes for the production of silicate glasses have been studied by analysing the luminescence decay profiles of ruthenium tris-(2,2'-bipyridine) in the presence of methylviologen. Two of the types were based on a low-and a high-pH catalyst while the third contained formamid
