Photoluminescence and fluorescence spectroscopy Scanning electron microscopy

HTM/In10-4 film · Thin Film

PL of perovskite contacting HTM or HTM/In10 films; top-view SEM images recorded on Hitachi SU 8000HSD.

Geometry: perovskite/HTM contact and top-view film imaging
Context: HTM control and HTM/In10 composite films.
Measurement source: 4 · 3. Results and discussion · Fig. 3

Property	Reported value	Normalised value	Uncertainty	Origin and quality	Source
Steady-state PL quenching trend	HTM/In10 devices show lower PL intensity than HTM; intensity decreases from 2 to 4 mg/mL then rises at 6 mg/mL	—	—	Text Qualitative	4 · 3. Results and discussion · Fig. 3a
HTM/In10 morphology trend with loading	films become less homogeneous with increasing In10; agglomerated mass appears on HTM/In10 surfaces	—	—	Text Qualitative	4 · 3. Results and discussion · Fig. 3c-f
