In this work we study the influence of the host matrix on the spectroscopic properties of Nd3+ions in 0.8CaSiO3-0.2Ca3(PO4)2eutectic glass and glass-ceramics obtained by the laser floating zone technique at different growth rates in the 100-500 mm/h range. Site-selective emission and excitation spectra of the 49/2→4F5/2,3/2transitions show the presence of a complex structure which suggests the existence of different crystal field sites for the rare-earth (RE) in these matrices. The spectra of the samples grown at lower rates show more structure and more resolved components. These experimental results suggest that Nd3+ions incorporate in a crystalline phase in these glass-ceramics.
