Synthesis and photoluminescence of ultra-pure α-Ge 3 N 4 nanowires

Pre-stages of the Formation of Ge3N4 on the Surface of Syngle-crystal Germanium in Hydrazine Vapors

“…Commercial hydrazinehydrate (50 mol% or 64 wt% N 2 H 4 ) was dehydrated by Raschig's method6 with modification: before distillation, it was boiled with NaOH in an inert N 2 atmosphere at 120℃ for 2 hours. The resulting liquid had a density (at 20℃) of ≅1.008 g/cm 3 and a refractive index of ≅1.471. It should be noted that the literature data on the physical characteristics of hydrazine (by which the concentration of water in it is estimated) differ from each other.…”

“…The interaction of hydrazine vapors with elemental germanium is one of the ways to obtain of germanium nitride (3Ge(s)+2N 2 H 4 (g)→ Ge 3 N 4 (s)+ 4H 2 (g)),a promising material in electronics, photocatalysis, luminescence, energy storage and others [1][2][3][4] . In 5 , the kinetics of interaction of hydrazine vapors with the surface of single-crystal germanium was studied using thermogravimetry.…”

Eu- and Tb-adsorbed Si3N4and Ge3N4: tuning the colours with one luminescent host

“…In most cases only Eu-and Tb-doped a-Si 3 N 4 thin lms and nanowires illustrating broad band emission are concerned. [33][34][35][36][37][38][39][40][41] Here we use the expression doping explicitly as this is given in the references.…”

Eu- and Tb-adsorbed Si3N4 and Ge3N4: Tuning the colours with one luminescent host

“…In most cases only Eu-and Tb-doped α-Si3N4 thin films and nanowires illustrating broad band emission are concerned. [30][31][32][33][34][35][36][37][38] Here we use the expression doping explicitly as this is given in the references.…”

“…(see supplement Figures S7-14 and corresponding section) This indicated that if some luminescence spectra may seem very similar overall at first sight, it turns out that definitely some changes are observed. [30][31] [32][33][34] [35][36][37] [38]…”
