High Resolution Low Temperature Spectra of Er(3+) in YAlO3.

Abstract

The absorption and emission spectra of erbium doped yttrium orthoaluminate (YAlO3:Er(3+)) have been recorded at 77K and 4.2K. A reduction of the data to tables of wavelengths and line strengths has been accomplished for experiments performed at 4.2K. Tables of observed line wavelengths are included. The wavelength ranges covered were 2175A - 9500A in absorption and 4500A - 9500A in fluorescence. A table of energy levels for Er(3+) in the YAlO3 host lattice is offered. A 'free ion' Hamiltonian parameter fit was performed (by computer) and the results are also listed. A brief outline of the theory of complex spectra is also included. (Author)
