“…We also observed white PL emission from a-CN x :H thin films prepared by microwave electron cyclotron resonance (ECR)-plasma chemical vapor deposition (CVD) and radio frequency (RF)-sputtering. 5,6) To modify the optical properties of a-CN x :H thin films, boron (B) doping of a-CN x :H is a promising approach since boron nitride (BN) has excellent optical and electronic properties, including a large band gap energy and negative electron affinity. [7][8][9] In particular, room temperature ultraviolet lasing at 215 nm has been observed for hexagonal boron nitride (h-BN) single crystals.…”

The structural and optical properties of boron (B)-doped amorphous carbon nitride (a-CNx) thin films with a B content of less than 10 at. % were investigated. The B-doped a-CNx thin films were synthesized by electron cyclotron resonance (ECR)-plasma chemical vapor deposition (CVD) by varying the substrate temperature and flow rate ratio of the source gases (BCl3/CH4/N2/Ar). An increase in the B content and a decrease in the Cl content were observed with increasing substrate temperature. The Tauc energy gap of the B-doped a-CNx thin films increased with decreasing C–N sp2 bond fraction and increasing B content. The photoluminescence (PL) peak position showed larger blue shifts and a tendency of increased integrated PL intensity was observed with increasing B content. These PL results suggest an increase in PL-active B-related sp2 C–C bond cluster density.

Graphite-like carbon nitride is a two-dimensional fluorescent material with discovered degradation of fluorescent properties. It was obtained by thermal decomposition of melamine and was studied using IR spectroscopy, transmission electron microscopy, and X-ray phase analysis. Three major fluorescence degradation mechanisms were identified. The first and the third ones are based on hydrogen addition to centres with an unshared electron pair, which leads to alteration of fluorescent properties and the second one is adsorption of water, which accumulates not only on the surface of the material but also probably permeates between the layers, thus leading to insignificant decrease of fluorescence.
