Luminescence of Tb3+/Eu3+ codoped LiYF4 single crystals under UV excitation for

The absorption spectra, excitation spectra, and emission spectra of Tb3t/Eu3t ions in LiYF4 single crystals synthesized by an improved Bridgman method are measured. The emission spectra of several bands, mainly located at blue ~487 nm (Tb:5D4 -> 7F6), yellowish green ~542 nm (Tb:5D4 -> 7F5), and red
