A comprehensive analysis was conducted on glass containing Eu2O3 and Dy2O3, or Eu2O3, Dy2O3, and CuO melted with nanodiamond powder. The analysis included measurements of optical absorption, photoluminescence emission and excitation spectra, and colorimetry. The study found that nanodiamond facilitated the stabilization of blue-emitting Cu+ and Eu2+ ions, along with yellow-emitting Dy3+ and red-emitting Eu3+ ions, resulting in white light-emitting glass. The proposed analysis methods provide helpful tools for understanding and designing materials for tunable white light-emitting devices.
A thorough analysis of glass containing Eu2O3 and Dy2O3, or Eu2O3, Dy2O3, and CuO melted together with nanodiamond powder was pursued based on measurements of optical absorption, photoluminescence (PL) emission and excitation spectra, and colorimetry. Nanodiamond facilitated the stabilization of Cu+ and Eu2+ ions with blue-emitting characteristics that, along with yellow-emitting Dy3+ and red-emitting Eu3+ led to the white light-emitting glass. Novel intensity notations implemented in intensity-based spectral ratios, and difference intensity correlation analysis were proposed for the assessment of PL properties. The chromaticity and correlated colour temperature of the emission were ultimately investigated as a two-parametric problem based on: (1) the different ionic components; and (2) the various excitation wavelengths employed. The optical analysis approach adds to the characterization methods to further fundamental understanding and provide helpful analytical tools for designing materials for tunable white light-emitting devices.
