摘要
Graphite-like carbon nitride nanowire bundles were synthesized from melamine via the solid state thermolysis at relatively low temperature（400℃）.Hexagonal carbon nitride tubes were prepared for the first time by heating the nanowire bundles at 550 ℃ 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.
