摘要: Abstract We demonstrate stable room-temperature electroluminescence at 1.54 μm under both forward and reverse bias conditions from erbium-doped silicon nanocomposites. also show enhanced tunable emission erbium when incorporated in porous based microcavities. Erbium is infiltrated the pores by cathodic electrochemical migration of ions followed high temperature annealing (600–1100°C) to produce a composite material made nanocrystals dioxide. The devices exhibit an exponential dependence as function driving current voltage. In bias, external quantum efficiency reaches 0.01%. large intensity. intensity decreases factor 24 2.6 increases 240 300 K. photoluminescence microcavity resonators more than one order magnitude tuned emit areas where natural very weak.
