Abstract

A bright red emission of manganese-doped BCNO (BCNO:Mn) phosphor was firstly synthesized by solid state method.

Solid-state nitrogen-doped carbon nanoparticles with tunable emission prepared by a microwave-assisted method

“…17,26,27 These p-conjugated systems play a crucial role in the energy level diagram of the CNP, which dictates their PL properties. 25,26 On the other hand, the sample prepared at 235 C showed a signicant decrease of N-H bonds (3200-3400 cm À1 ), accompanied by increase of the C-H sp 3 and C]O bonds at 3060 cm À1 and 1680 cm À1 , respectively. The observation of the signatures of these functional groups suggests the carbonization of the sample.…”

“…Carbon-based phosphors, such as carbon nanoparticles (CNPs), carbon dots, graphene quantum dots, and boron carbon oxynitride (BCNO), have gained scientic interest in various semiconductor applications, such as biosensing, bioimaging, nanomedicine, solar cells, and catalysis. [1][2][3][4][5] Owing to their superior properties (tunable photoluminescence emission, high quantum efficiency, low cytotoxicity, facile production, costeffective preparation, photostability, chemical inertness, and excellent biocompatibility), carbon-based phosphors are expected to be excellent potential substitutes for semiconductor quantum dots and rare earth element-based phosphors. [6][7][8] Among other carbon-based phosphors, carbon nanoparticles (CNPs) are the most promising materials for large-scale production due to their scalable and facile synthesis with superior properties.…”

Preparation and enhanced adsorption properties for CO2 and dyes of amino‐decorated hierarchical porous BCN aerogels

“…BCN precursor presents peaks at 3179, 3335, 3412, and 3490 cm −1 assigned to the amino functional groups 25 . And the peak at 3518 cm −1 can be assigned to the O‐H bond, the fingerprint region from 1650‐500 cm −1 range can be assigned to vibrations of B‐O, C‐N, C‐O, and C‐C groups 26 . In the case of BCN, the B‐N stretching vibration was obviously weaker and the B‐N‐B bending vibration was hardly visible, which may originate from the doping of carbon weakened the vibration of B‐N and introduced other miscellaneous bands.…”

Microwave-assisted reduction method under nitrogen atmosphere for synthesis and electrical conductivity improvement of reduced graphene oxide (rGO)

“…This is shown by the vast use of carbon-based nanostructured materials, which include carbon nanotubes, 2,3 fullerenes, 2,3 nanodiamonds, 3 graphene quantum dots, 4 reduced graphene oxide (rGO), 5 carbon dots, 6 and boron carbon oxynitride (BCNO) phosphor materials. 7 These carbon-based nanostructured materials are exciting research subjects due to their excellent mechanical strength, electrical and thermal conductivity, optical properties, low toxicity, tunable color emission, and chemical inertness. 2,8,9 They offer high potential for various applications, such as drug delivery systems, tissue scaffold reinforcement, catalysts, light emitting diodes (LED), panel displays, bio-imaging, DNA labeling, and energy storage materials.…”
