Luminescence properties of Dy3+ and Sm3+: Potassium lithium borate glass
The present paper describes the spectral properties of Sm3+ (0.4 mol%) and Dy3+ (0.4 mol%) ions-doped 20Li2O-10K2O-70B2O3 glasses. X-ray diffraction method was use to confirm the amorphous phase of samples. The physical properties have been determined based on UV absorption spectra. The hypersensiti...

| Summary: | The present paper describes the spectral properties of Sm3+ (0.4 mol%) and Dy3+ (0.4 mol%) ions-doped 20Li2O-10K2O-70B2O3 glasses. X-ray diffraction method was use to confirm the amorphous phase of samples. The physical properties have been determined based on UV absorption spectra. The hypersensitive transition of Dy3+ and Sm3+ is found due to transition of (6F11/2,6H9/2) and (6F7/2), respectively. The emission bands of Dy3+: glass has shown around 572 nm, 612 nm and 646 nm; these emissions are attributed to the transitions of 4F9/2 →6H15/2 (yellow), 4F9/2 - 6H13/2 (red) and 4F9/2 -6H11/2 (red). With regard to Sm3+: glass has three emission bands those have been generated from 4G5/2 → 6H5/2 (616 nm), 4G5/2 → 6H7/2 (660 nm) and 4G5/2 → 6H9/2 (719 nm) transitions. The current results promise several applications in optical fields such as UV-sensor, developing new color light sources and tunable visible lasers |
