Abstract

A constant voltage electrochemical doping method and the efficient upconversion emission of porous silicon (PS):Er/Yb, emitting in the red, green, and ultraviolet regions at room temperature were presented. The beneficial effect of PS as a host matrix for Er-Yb complexes, enhancing the emission processes was observed. The presence of pores allows a greater concentration of Er and Yb to be doped into it. The results show that the efficient enhancement of red and green upconverted emissions and the appearance of UV emission are due to efficient energy transfer between Yb and Er.
