We report a new way to enhance the photoluminescence of porous silicon(PS) in red light(625 nm) under room temperature by doping the rare earth(Yb) in porous silicon with distributed Bragg reflection (DBR) structures. It is observed that a suitable concentration of Yb3+ ions could enhance the photoluminescence of porous silicon effectively. Compared with the single-layer porous silicon film, the enhancement of Yb-doped PS photoluminescence from porous silicon DBR structures is higher. RE doping and DBR structures could double strengthen PS photoluminescence..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
