Ta2O5 is among the high-refractive-index materials frequently used in optical coatings, from antireflective to guiding thin films in waveguides operating at high temperatures, due to broad-spectrum transparency and high thermal and chemical stability.
“Owing to a broad-spectrum transparency and high thermal and chemical stability, tantalum pentoxide (Ta2O5) is among the high-refractive-index materials frequently used in optical coatings, from antireflective to guiding thin films (cores) in waveguides operating at high temperatures [45-48].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
