Optical properties investigation and multicolor behavior of neodymium (Nd)-doped oxyfluoride silicate glasses SiO-PbO-PbF.

The aim of this research is to investigate novel compositions of oxyfluoride glasses doped with Neodymium (Nd) rare earth ions in the visible spectrum. This area has not been extensively studied in the existing literature, so it is vital to understand the favorable photoluminescence characteristics within this part of the electromagnetic spectrum. Therefore, we synthesized and characterized SiO-PbO-PbF (SPF) doped with 1% neodymium (Nd) ions glasses.

Luminescence properties of CdF single crystals co-doped with Er and Y ions.

The luminescence properties of erbium and yttrium co-doped cadmium difluoride with three different concentrations of yttrium were investigated. First, we synthesized single crystal samples with good optical quality using the Bridgman technique. From the optical absorption spectra, recorded at room temperature, both in the ultraviolet-visible and infrared spectral ranges, Judd-Ofelt analysis was performed based on yttrium concentrations to predict the radiative properties of Er luminescent ions.
