Ambient pressure, low-temperature synthesis and characterization of colloidal InN nanocrystals

Abstract

Highly soluble, non-aggregated colloidal wurtzite InN nanocrystals were obtained through an ambient pressure, low-temperature method followed by post-synthesis treatment with nitric acid.

Surface and bulk electronic properties of low temperature synthesized InN microcrystals

“…There are indeed efforts in this direction. InN microcrystals have been synthesized by solvothermal technique using various precursors and solvents at temperatures ranging from 240 to 280 1C [6][7][8]. However, it should be noted that most of these studies deal with the chemistry aspects of the synthesis process and a few basic characterization.…”

Synthesis of InN nanoparticles by rapid thermal ammonolysis

“…Even though these techniques utilize very sophisticated equipment, many difficulties have not yet been overcome due to the low decomposition temperature of InN. Recent works published on the synthesis of InN nanoparticles are based on solvothermal methods at elevated pressure and temperatures (Wu et al 2005;Xiao et al 2003), metathesis reactions (Bai et al 2002), decomposition of nitrogen-containing indium compounds (Schofield et al 2004), or reactions of sodium amide with indium halogenide at elevated temperatures (Hsieh et al 2010). The synthesis of InN nanostructures using indium oxide ammonolysis has also been reported (Schwenzer et al 2004).…”

Colloidal III–V Nitride Quantum Dots

“…Although several synthesis methods, such as solvothermal methods [24,25], sputtering [26], and molecular beam epitaxy (MBE) [27], were developed to prepare 0D InN QDs, more effort needs to be devoted to improve the quality of InN QDs with a controlled way.…”

“…Hsieh [25] also used solvothermal to prepare the InN NCs with an average diameter of 6.2 AE 2.0 nm utilizing InBr 3 and NaNH 2 in a low temperature, ambient pressure, and liquidphase condition.…”

“…Over the past 20 years, many groups have prepared the colloidal III-V nitride quantum dots by various solution-based methods. These methods can be classified into the following approaches, namely solvothermal [24,25,34], hydrothermal [35], and thermal decomposition of single [36,37] and two precursors [38]. The hydrothermal process refers to the reaction of reactants and water in a pressurized reaction environment to form nanoparticles.…”
