Crystal field splitting and effective g factor of infrared emission band in Er3+:YVO4Er3+:YVO4 single crystal

• Strong multiple emission lines in 1550 nm region had been observed in Er3+:YVO4Er3+:YVO4 single crystals.
• Crystal field theory models were built to analyze the crystal field induced- and magnetic field induced- energy splitting.
• The calculations agree well with the experimental results.
• The understand of energy structure in Erbium doped materials are important for their applications in optoelectronics.

Strong multiple emission lines in 1550 nm region had been observed in Er3+:YVO4Er3+:YVO4 single crystals. A magnetic field up to 5 T was applied onto the sample to further tune the energy structures. Then crystal field theory models were built to analyze the crystal field induced- and magnetic field induced-energy splitting. In the models, both the coulomb potential between the ions and the magnetic Hamilton energy were considered as perturbations. Comparison between the experimental and theoretical results demonstrates that the calculations agree well with the experimental results. Furthermore, the calculation methods proposed here can also help people better understand the interactions between the ions and the fields, and open up a way to tailor the spectral output of the crystals, which is very important for design of wavelength division multiplexing optoelectronics and telecommunication devices.

Strong multiple infrared emission lines had been observed in Er3+:YVO4Er3+:YVO4 single crystals. And crystal field theory models were successfully built to analyze the observed crystal field induced- and magnetic field induced- energy splitting.Figure optionsDownload as PowerPoint slide
