Abstract
This study examines the photoconductivity of solution-synthesized Bi2O2S nanostructures, with or without hydrazine hydrate (HH). HH produces thinner nanostructures with faster carrier trapping times due to surface defects. Both samples show similar bulk trapping and recombination times, with longer rise times possibly indicating enhanced exciton binding energies from confinement to two dimensions. This approach promises to modulate photoconductivity in layered materials by adjusting reducing agent amounts during synthesis.
