Polyoxometalate Complexes as Precursors to Vanadium‐Doped Molybdenum or Tungsten Oxide Thin Films by Means of Aerosol‐Assisted Chemical Vapour Deposition
Bibliographic record
Abstract
Abstract Aerosol‐assisted chemical vapour deposition of substituted polyoxometalates H4[PMo11VO40], H7[PMo8V4O40], [nBu4N]4[PVW11O40] and [nBu4N]5[PV2W10O40] resulted in the formation of vanadium‐doped metal oxide thin films. Depositions were carried out at 550 °C in methanol or acetonitrile for the POMs that contained molybdenum or tungsten, respectively. The as‐deposited films were X‐ray amorphous and relatively non‐adherent. However, on annealing in air at 600 °C, decolourised translucent films that were more mechanically robust were obtained. Films deposited from H4[PMo11VO40] and H7[PMo8V4O40] consisted of V‐doped MoO3 in the orthorhombic phase and films from [nBu4N]4[PVW11O40] and [nBu4N]5[PV2W10O40] comprised of monoclinic V‐doped WO3. All films were fully characterised by using X‐ray photoelectron spectroscopy, energy‐dispersive X‐ray diffraction, scanning electron microscopy and UV/Vis spectroscopy.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
