Hypersensitive transitions of Tm3+, Ho3+ and Dy3+ rare-earth ions in garnet crystals

In this work, spectroscopic characteristics (oscillator strengths, intensity parameters) of intermanifold f–f transitions of Tm3 +, Ho3+and Dy3+ions in garnet crystals are investigated. It has been found that the intensity change of the hypersensitive intermanifold f–f transitions of rare-earth ions...

Description
Summary:In this work, spectroscopic characteristics (oscillator strengths, intensity parameters) of intermanifold f–f transitions of Tm3 +, Ho3+and Dy3+ions in garnet crystals are investigated. It has been found that the intensity change of the hypersensitive intermanifold f–f transitions of rare-earth ions in garnet crystals is determined by the characteristics of their local environment. ► The intensities of transitions of Tm3+, Ho3+, Dy3+ ions in garnet crystals were determined. ► The hypersensitive transitions of these ions in Ca3(NbGa)5O12 are characterized by high values of intensity. ► This fact is explained by presence of rare earth ions with local symmetry C2, C2v, C1 in Ca3(NbGa)5O12 crystals.
