Abstract

Sputter-deposited thin-film amorphous AlN : Er ( 1 at . % ) emits at 554 and 561 nm as a result of H 11 / 2 2 I 15 / 2 4 and S 3 / 2 4 I 15 / 2 4 transitions. AlN : Yb ( 1 at . % ) gives a weak emission peak at 966 nm as a result of F 5 / 2 2 F 7 / 2 2 . The codoping of Er and Yb in AlN results in energy transfer from Er + 3 to Yb + 3 and enhances the Yb + 3 emissions by an order of magnitude. Transfer of electrons occurs from the S 3 / 2 4 state of Er + 3 to the F 5 / 2 2 state of Yb + 3 . The weak emission from Yb + 3 , when excited by a 532 nm laser in the absence of Er + 3 , confirms that the luminescence enhancement in ytterbium is due to energy transfer and not to direct green light excitation by the erbium emission. A possibility of population inversion and a four-level laser cavity formation exists in the Er + 3 Yb + 3 system.
