Synthesis and formation mechanism of cubic boron nitride nanorods in lithium bromide molten salt

“…Although successful syntheses of hBN nanorods [19] and patterned conical [20] nanorods have been reported, the synthesis of one-dimensional cBN nanorods (cBNNRs) was rarely investigated. It was reported that cBNNRs with diameters of 50-200 nm were prepared by the benzene thermal method [21].…”

Eu‐doped Boron Nitride Nanotubes as a Nanometer‐Sized Visible‐Light Source

“…Peak I is the typical CL emission from the hexagonal BN structure or multiwalled cylindrical BNNTs. [11,20,21] The near-UV light emission is generated by the high-energy electrons. Peak II is most likely associated with the special bamboo structure, as the emission at the same energy range is observed from BN nanohorns, [22,23] which have a large number of bent BN layers and associated defects similar to the cup-shaped BN layers in the bamboo tubes.…”

Low‐Temperature Synthesis and Growth of Hexagonal Boron‐Nitride in a Lithium Bromide Melt

“…17 This makes hBN one of the most favored candidates for compact ultraviolet laser devices, and expands its application potential to include optical storage, photocatalysis, nanosurgery, and ophthalmic surgery.In recent years, there have been increasing efforts toward synthesizing boron-nitride nanomaterials with specific morphologies because of the expectation of novel properties, such as nanotubes, 18-20 nanomesh, 21 monolayer, 22 nanorings, 23 nanofibers, 24 and nanorods. 25 An understanding of the growth behavior is essential to obtain different hBN crystals with specific morphologies. Solozhenko et al 26 first reported the solution method, by which the graphite-like boron nitride crystals had been produced in solutions of supercritical N-H fluids at pressures up to 5.2 GPa and temperatures up to 13271C.…”
