Abstract: | The absorption and luminescence spectra of gadolinium gallium garnet crystals activated with Mn during high-temperature solution growth are analyzed in relation to the valence state of Mn. The results indicate that, in contrast to melt growth, the flux growth process stabilizes manganese in the valence state 3+. |
