Intense green and red emissions are observed in Er3+ singly-doped and Er3+/Yb3+-codoped NaYF4 phosphors under 808nm excitation. Co-doped Yb3+ ions reduce Er3+ up-conversion emission at low Er3+ doping concentration, while they enhance the up-conversion emission at relatively high Er3+ concentration. A competitive energy transfer mechanism between Yb3+ → Er3+ and Er3+ → Yb3+ is proposed to explain the Yb3+ dependent Er3+ up-conversion behavior..

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.
