Abstract:

Graphite-like carbon nitride nanowire bundles were synthesized from melamine via the solid state thermolysis at relatively low temperature(400 °C). Hexagonal carbon nitride tubes were prepared for the first time by heating the nanowire bundles at 550 °C in argon atmosphere. The forming process of tubes and transformation of the molecular structures from s-triazine rings to tri-s-triazine units were analyzed. The blue and yellow-green emission photoluminescent(PL) properties of the products were investigated in detail, and the reasons for the differences of PL properties between the bundles and tubes were discussed.

Key words: Carbon nitride; Solid-state synthesis; Photoluminescence; Melamine
