The luminescence and decay enhancement by variation in atomic size of alkaline earth metals in Pr3+ incorporated sodium lead borate glass

The glasses used for the present study are prepared by the melting and quenching techniques of composition 20Na2O−10PbO-10MO-60B2O3−xPr2O3 (where, M=Ba, Ca, Sr and x= 0.5 mol% of Pr3+). For different alkaline considered with same Pr3+ concemtartion incorporation on present work as resulted in interesting facts. Due to the effect of different atomic size, the luminescence and life time of glasses are affected. Only for calcium alkaline earth metal incorporated samples has proved to have highest intensity in emission and longer life time. The detailed studies of them have been reported for the better understanding

Luminescence Behaviour and Decay Lifetimes of Different Alkaline Earth Metals in Sodium Lead Fluoro-Borate Glass Doped with Pr3+

The glasses with embedded 0.5 mol% of Pr3+ in the composition 20Na2O-5PbF2-5PbO-10MO-(60-x) B2O3-xPr2O3 (where, M=Ba, Ca, Sr) were prepared using melting and quenching techniques. In Na2O-PbF2-PbO-BaO-B2O3 glasses, the BaO is replaced by CaO and SrO showed that for different alkaline in the same host glass resulted in the interesting facts. Luminescence spectra and time decay measurements were made to examine the influence of different alkaline earth metals ions. The variations of optical properties with different alkaline in same host glass are discussed and results leads to an interesting facts. The detailed studied made and have been reported for the better understanding
