Abstract

Spectroscopic properties of Cr doped silicate and aluminate glasses were compared with Cr: forsterite. Emissions were found at 970nm in silicate glass and 1170nm in aluminate glass. The 970nm emission was attributed to Cr³⁺⁴T₂ and 1170nm emission to Cr⁴⁺³T₂. The energy transfer from Cr³⁺⁴T₁ to Cr⁴⁺³T₂ and Cr⁴⁺³T₁ to Cr³⁺⁴T₂ were found in Cr: forsterite.
