Growth control of HgI 2 NCs was investigated by Atomic Force Microscopy (AFM), Optical Absorption (OA), Fluorescence (FL), and X-ray diffraction (XRD). AFM images reveal the formation of HgI 2 nanocrystals in host glass matrix. HgI 2 NCs growth was evidenced by an OA and FL band red-shift with increasing annealing time. XRD measurements revealed the b crystalline phase of the HgI 2 nanocrystals. V C 2014 AIP Publishing LLC.

Preparation of Nanostructured HgI2 Nanotubes/Si Photodetector by Laser Ablation in Liquid

“…demonstrates the PL spectrum of HgI 2 colloids exited with laser source of 300nm wavelength, the spectra show the existence of only single PL emission centered at 535nm (2.31eV). This value is smaller than the optical energy gap determined from UV-VIS results due to the effect of trapping defects inside the band gap of HgI 2 [14]. Fig.…”

Исследование фотофизических свойств нанокомпозита HgI-=SUB=-2-=/SUB=-@mSiO-=SUB=-2-=/SUB=-

“…Особый интерес представляют люминесцентные свойства полупроводниковых наноточек. Проведенные в связи с этим исследования люминесцентных свойств наноточек слоистых полупроводни-ков [11][12][13] показывают, что они существенно зависят от условий синтеза наночастиц.…”
