dc.identifier.citationRecovery behavior of the luminescence peak from graphitic carbon nitride as a function of the synthesis temperature/ Eugene B. Chubenko [and other] // Crystal Research &Technology. – 2020. – Vol.55, Iss.3. – P. 1900163. - DOI: 10.1002/crat.201900163.ru_RU
dc.description.abstractGraphitic carbon nitride (g-C3N4) is synthesized by thermal decomposition of thiourea and subsequent in situ polymerization of the products in the oxygen-containing ambient at 450–625 °C. The synthesized material contains oxygen at a concentration increasing with the processing temperature from 4.8 to 9.8 at %. The photoluminescence peak is found to be red-shifted with the temperature increased to 575 °C becoming then blue-shifted at higher temperatures. The observed red-shift of the photoluminescence peak is supposed to be caused by band-gap narrowing in g-C3N4 doped by oxygen while its recovery behavior is controlled by thermally induced oxygen-assisted disruption of sp2 bonds in C-N 𝝅-orbital conjugated system of tri-s-triazine units building polymer sheets in g-C3N4.ru_RU
