Abstract

Using electrochemically prepared porous Si with hydride covered internal surfaces, we determine the H-content by thermal effusion and measurement of the total gas evolution. The amount of Si is obtained by weighing. In this way, we derive a value of the ratio of H- to Si-atoms and from the latter a value of the linear dimension of the luminescing particles
