Novel NIR emission 4 G 5/2 to 6 F 11/2 and efficient multichannel emissions of Sm 3+ doped GeO 2 -PbO glass

Investigation of Sm3+-doped PBNaG glasses for orange LED applications

“…The decay process has a non-exponential nature due to cross-relaxation through multi-polar interactions between Sm 3+ ions. The lifetimes of the energy levels can be determined experimentally by measuring the emission decay from each of the 4 G 5/2 → 6 H 7/2 transitions [25,26]. When Sm 3+ is excited by an excitation wavelength, a relaxation non-radiation rapidly extends to fluorescent energy levels because of the gap energy [27].…”

High-Pressure Effect in Vis–NIR Emission of Sm3+-Doped GeO2–PbO Glasses

“…In recent years, heavy metal glasses have been investigated as suitable hosts since they present large solubility for RE 3+ ions, relatively low phonon energy, large optical transparency in the visible and infrared regions, good thermal stability and high refractive index. − …”

Photoluminescence and X‐Ray‐Induced Luminescence Behavior of Sm2O3‐Doped Oxyfluoroborate Scintillating Glass for Radiation Detecting Material

“…6 H 9/2 transition is higher than those in PKAMfNfSm1.0, [49] PKACfNfSm1.0, [50] S29AYLSm1.0, [51] B20BiNCfSm0.5, [45] and PKAZfLfSm1.0 [52] glasses and lower than the KNSZLSm10 [19] and GPbSm1.0 [50] glasses. Moreover, the optical gain value of 30.52 Â 10 À22 cm 2 s calculated for the present ANCBSm0.5 glass is relatively higher than those in the PKACfNfSm1.0, [49] GPbSm1.0, [50] S29AYLSm1.0, [51] B20BiNCfSm0.5, [45] PKAZfLfSm1.0, [52] and KNSZLSm10 [19] glasses and also similar to that of the PKAMfNfSm1.0 glass. [49] According to the aforementioned results, the larger σ e (14.13 Â 10 À22 cm 2 ) and longer optical gain (30.52 Â 10 À22 cm 2 s) for the 4 G 5/2 !…”

“…6 H 9/2 transition suggest that the ANCBSm0.5 glass could be a potential application in optical amplifier devices. [19,45,[49][50][51][52]…”
