Abstract
Photoluminescence in the 1.2–1.35 μm range has been observed in silicon substrates incorporating thulium in the trivalent Tm3+ state and co-doped with boron. The results showed eight sharp lines at 1211.5, 1231.0, 1250.8, 1269.3, 1283.8, 1290.6, 1311.3 and 1326.0 nm, corresponding to known internal Tm3+ transitions in the manifold from the 3H5 to the 3H6 ground states. The luminescence was strongly dependent on the sample fabrication processes. In this paper we will discuss the influence of Tm implantation parameters and post-implant annealing conditions on the photoluminescence response of silicon doped with Tm3+.
