Time resolved spectroscopy of Ni2+ doped fluoroclorozirconate glasses

摘要: Abstract Optical absorption, time resolved luminescence and fluorescence decay measurements of Ni2+-doped fluoroclorozirconate glasses are reported. Time were taken exciting the samples at different wavelengths. The position orange emission band (1T2g(D) → 3A2g(F)) moves to blue when excitation is changed higher energies. For a fixed wavelength, also measurement after laser pulse increases. decays non-exponential depend detection wavelength. They slower for shorter results show distribution Ni2+ sites with ‘crystal field’ environments.
