Abstract
A composition of precursors for the release of vapors of alkali or alkali-earth metals is described. The composition has at least a compound of alkali or alkali-earth metal, at least a reducing agent and optionally an absorbing material, all in the form of powders, dispersed in a viscous matrix of hybrid organic-inorganic type. Dispensers for the release of these metals obtained through the composition and micro-electronic devices are also described.
