Structure and Optical Properties of Nd3+-Doped Multicomponent Borosilicate Glass

Therelationship between the optical properties and structural changes of aluminoborosilicate (ABS) glass doped with Nd3+ ions is studied. The luminescence and electron paramagnetic resonance spectra are analized in dependence on Nd2O3 concentration and irradiation dose. Variations are observed in the shape of the emission band corresponding to the F-4(3/2) -> I- 4(9/2) transition and the ratio of its Stark components both with an increase in the concentration of the dopant and with an increase in the radiation dose. Analysis of the EPR spectra in the region of radiation defects of the borosilicate matrix (g similar to 2), measured at the temperature of helium, reveals modifications in the signal of paramagnetic activity attributed to these defects. The absence of the structure of the EPR band, for which boron-oxygen-hole centers (BOHCs) of borosilicate glass are responsible, is found. The dependence of the shape and position of this signal on the Nd2O3 concentration is also observed. The results obtained agree with the presence of various local environments of the Nd3+ ion in the structure of multicomponent borosilicate glass.

Automated summary

The relationship between the optical properties and structural changes of aluminoborosilicate (ABS) glass doped with Nd3+ ions was studied, with variations observed in luminescence and electron paramagnetic resonance spectra depending on Nd2O3 concentration and irradiation dose. Modifications in emission band shape and position, as well as EPR signal, were found in relation to the concentration of the dopant.
