Abstract

In this report, we describe the growth mechanism and emission characteristics of an Er₂SiO₅ superlattice crystal, which is a promising light source for silicon photonics. This crystalline compound contains a high proportion of Er ions (above 20 at%) as the constituent element, resulting in the prevention of concentration quenching, and exhibits fine structure in its PL spectrum even at room temperature. The Er₂SiO₅ superlattice crystal is formed by phase separation, and does not agree with the phase diagram of rare-earth silicates reported previously. Because of this, highly oriented Er₂SiO₅ superlattice crystal thin films can be obtained on Si substrates. We propose the use of Er₂SiO₅ nanocrystallites embedded in SiO_x produced by phase separation growth as a novel light source for silicon photonics.
