Abstract

The luminescent quantum efficiency of Yb3+ ions in lithium niobate (LiNbO3) is obtained by use of a method based on the simultaneous and multiwavelength measurement of photoacoustic and luminescent signals after modulated continuous laser excitation. The experimental results give a high value for the luminescence quantum efficiency (Φ = 0.90 ± 0.05), coincident with the predictions by the comparison between experimental and estimated radiative lifetimes.
