Abstract:
The experimental results of luminescence measurements in Ca3Al2O6 : Tb showed single excitation wavelengths at 246 and 278 nm in the UV region. For the 278 nm excitation, six distinct emission peaks were found at 378, 419, 437, 447, 487 and 544 nm. Some spectroscopic parameters were calculated using CIE coordinates showing emission in the near-blue region, which may be useful for various display devices.
