“…Current results showing reduction in the bandgap energy in the case of all materials and specifically for spin‐coated thin films are in conformity with the previous investigations using lanthanide dopants for bandgap tuning. [ 8,19 ]…”

“…Current results showing reduction in the bandgap energy in the case of all materials and specifically for spin-coated thin films are in conformity with the previous investigations using lanthanide dopants for bandgap tuning. [8,19] The optoelectronic properties of the Ta 2 O 5 host have been enhanced as observable from the reduction in the bandgap energy which is attributable to the lanthanide doping. Similar results have been obtained in other studies where lanthanide ions were used for improving the optical and electronic aspects of the metallic oxides.…”

“…The performance of the SiO 2 -Ta 2 O 5 host material was considerably augmented using lanthanide triple doping mechanism utilizing different combinations like Er 3þ / Yb 3þ /Tm 3þ , Er 3þ /Yb 3þ /Nd 3þ , and Er 3þ /Tm 3þ /Nd 3þ . In another report by Saggioro et al, [8] the optical performance of the Ta 2 O 5…”

“…The performance of the SiO 2 ‐Ta 2 O 5 host material was considerably augmented using lanthanide triple doping mechanism utilizing different combinations like Er 3+ /Yb 3+ /Tm 3+ , Er 3+ /Yb 3+ /Nd 3+ , and Er 3+ /Tm 3+ /Nd 3+ . In another report by Saggioro et al, [ 8 ] the optical performance of the Ta 2 O 5 crystal fibers was improved using Eu 2 O 3 via laser‐heated pedestal technique for growing crystals. Lanthanide doping has also been associated with the structural modification and mechanical strength improvement of the host material.…”
