“…Liquid phase NC materials synthesis includes processes, such as rapid solidification [58][59][60][61], electrodeposition [62][63][64], chemical precipitation [65,66], and sol-gel technique [67][68][69]. NC material synthesis in gaseous form is achieved by inert gas condensation [70][71][72], vapor deposition/sputtering [73][74][75][76][77], and plasma processing [78]. Recently, scholars have diverted their research interests towards several unconventional methods to produce nanocrystals using biological cells [79].…”

Nanostructuring is a commonly employed method of obtaining superior mechanical properties in metals and alloys. Compared to conventional polycrystalline counterparts, nanostructuring can provide remarkable improvements in yield strength, toughness, fatigue life, corrosion resistance, and hardness, which is attributed to the nano grain size. In this review paper, the current state-of-the-art of synthesis methods of nanocrystalline (NC) materials such as rapid solidification, chemical precipitation, chemical vapor deposition, and mechanical alloying, including high-energy ball milling (HEBM) and cryomilling was elucidated. More specifically, the effect of various process parameters on mechanical properties and microstructural features were explained for a broad range of engineering materials. This study also explains the mechanism of grain strengthening using the Hall-Petch relation and illustrates the effects of post-processing on the grain size and subsequently their properties. This review also reports the applications, challenges, and future scope for the NC materials.

“…Its density is noted to be at 2.9-3.3 g/cm 3 and has a high melting point of about 2000 ℃ [2][3]. Aluminum nitride in its pure form exists in colorless form with a certain level of glow, but with the integration with other elements, dopants, and impurities it can give color [4]. Though AlN possesses covalent bonds, ionic characteristics also exist.…”

Well dispersed Aluminum Nitride (AlN) nanopowder and AlN thin film were compared to observe their structural and luminescence properties. AlN thin films were deposited on silicon and copper substrates by RF magnetron sputtering. PL peaks analysis indicated the same pattern of emission peaks over different excitation wavelengths ranging from 200 nm to 300 nm for both the AlN nanopowder and thin film, nearly 100 -1000 times PL increment observed in AlN nanopowder. It is suggested that the reason for PL of AlN material is due to surface defects and impurities like oxygen-related point defects (O+N), nitrogen vacancies (VN), the transition from the donor level of VN (nitrogen-vacancy) to the acceptor level of AlN (antisites defects), and various defect complexes (V3-Al – 3 O+N) are responsible for the enhanced observed emission peaks. With well-defined emission curves, AlN Nanopowder and thin films are observed to be good substrate and insulator material for microelectronic circuits, Light Emitting Diodes, Laser Diodes, and in biomedical applications such as bioimaging and biosensors.
