The control of luminous radiation has extremely important implications for modern and future
technologies as well as in medicine. In this Review, we detail chemical structures and their …

Chemically derived graphene oxide (GO) is an atomically thin sheet of graphite that has
traditionally served as a precursor for graphene, but is increasingly attracting chemists for its …

Amorphous silicon quantum dots (a-Si QDs), which show a quantum confinement effect
were grown in a silicon nitride film by plasma-enhanced chemical vapor deposition. Red …

Photoluminescence (PL) from surface-oxidized Si nanocrystals (nc-Si) was studied as a
function of the size. The size of nc-Si was comparable with or larger than the Bohr radius of …

Nitrogen (N)-doped graphene with different atomic percentages (2.3–4.7 at%) of N has been
synthesized by thermal annealing of reduced graphene oxide (RGO) in ammonia gas for …

This paper reviews new approaches to size‐controlled silicon‐nanocrystal synthesis. These
approaches allow narrowing of the size distribution of the nanocrystals compared with those …

Silicon (Si) nanomaterials with bright luminescence in the visible region are promising
materials for use as the next-generation light source in displays, lighting, and biomedical …

We report a photoluminescence study of silicon nanoclusters produced by laser ablation. It
was found that by varying the preparation parameters it was possible to change the mean …

We investigated the near-band-edge optical responses and photocarrier dynamics of
encapsulated long-term stable CH3NH3SnI3 (MASnI3) thin films and solar-cell devices. The …

This work discusses the recombination mechanisms and the chemical nature of the emitting
centers subjacent to the white-light emission of sol− gel derived amine-functionalized …
