摘要：

The luminescence mechanism of Nd3+: B2O3-Al-2-O-3 -CaO glasses with different amounts of B2O3 were investigated based on their electron paramagnetic resonance spectra and luminescence properties. The results of the echo-detection field sweep exhibited two different maxima indicating that Nd3+ ions occupy two different sites. Al-27 and B-11 signals in two-dimensional hyperfine sublevel correlation spectra were observed in the ( + , +) quadrant, indicating that both Al-27 and B-11 are located in the second or higher order Nd3+ coordination shell. In addition, the fraction of the B-11 nucleus present in the Nd3+ coordination sphere increased with an increase in the amount of B2O3. The continuous changes in the hypersensitive transition intensity and luminescence properties are strong indicators for the change in the Nd3+ coordination environment.
