Orange color emitting Sm3+ ions doped borosilicate glasses for optoelectronic device applications

摘要: Abstract An intense orange color emitting Sm3+ activated Li2O–PbO–ZnO–Al2O3–B2O3–SiO2 (LPZABS) glasses were propitiously fabricated by using sudden quenching method to study the luminescent potentiality spectroscopic techniques such as XRD, FT-IR, optical absorption, photoluminescence (PL) and PL decay. XRD FT-IR reveals glassy nature various functional groups present in LPZABS host glass respectively. Judd-Ofelt parameters derived from absorption spectra are used estimate radiative for excited states of ions glasses. Under 400 nm excitation, luminescence prepared exhibit three emission bands that corresponds 4G5/2 → 6H5/2 (562 nm), 4G5/2 → 6H7/2 (598 nm) 4G5/2 → 6H9/2 (645 nm) transitions ions. Among these three, transition observed region is relatively more prominent. The decay curves recorded 4G5/2 fluorescent level reveal exponential behavior single fitting applied evaluate experimental lifetimes ( τ exp ). values found be decreasing with ion content due cross-relaxation energy transfer process. results can effectively fabricating visible optoelectronic devices.
