Chapter 2 Optics of the 4f → 4f and 4f → 5d transitions in crystals
The following sections are included:
-
Optical properties of RE ions in crystals
-
Selection rules for the magnetic-dipole and electric-dipole optical transitions in RE ions in crystals
-
Theory of intensities of “forbidden” RE3+ electric-dipole 4f → 4f transitions in crystalline hosts
-
Modern experimental methods of measuring the 4f → 4f optical spectra of RE compounds: site-selective polarized spectroscopy (SSPS) and “hot-band” spectroscopy
-
Explanation regarding parity-allowed 4f → 5d optical transitions in RE ions within the framework of the “strong-weak” crystalline field approximation
