Properties of Carbon Dots Synthesized Solvothermally from Citric Acid and Urea
We propose a simple one-stage method to prepare carbon dots using citric acid as a carbon source and urea as a nitrogen source. It is shown that luminescence spectra of carbon dots depend on the excitation wav...

Hydrothermal Synthesis of Luminescent Carbon Dots from Glucose and Birch Bark Soot
Carbon dots were prepared by the method of hydrothermal synthesis from carbon precursors of glucose and birch bark soot in aqueous ammonia. The distribution of lateral sizes of carbon dots testifies their aver...

Investigating the Properties of Graphite Oxide Suspension, Films, and Papers Produced from Natural Graphite of Southern Yakutia
An aqueous suspension of graphite oxide (GrO) was prepared from natural Yakut graphite by modified Hummers′ method. The lateral size of GrO flakes varied from 0.1 μm to 10 μm, their thickness was 20 nm. The fa...

Graphene-oxide films printed on rigid and flexible substrates for a wide spectrum of applications
Structures of films produced from a water-based graphene oxide ink by 2D printing on various substrates, including those of the flexible type, are compared. It was shown that the deposition of a thin polyvinyl...

Thin partially reduced oxide-graphene films: structural, optical, and electrical properties
High-resistive (1012 Ohm/□) oxide-graphene films with thickness varying from 5 nm to several micrometers were produced and studied. Films of 5–150 nm on glass had a transparency of 93–98% for wave-lengths of 400–...
