Multi-morphological growth of nano-structured In2Se3 by ambient pressure triethylene glycol based solution syntheses

In2Se3 Nanocubes as High Current Density Cold Cathode Materials

“…Indium selenide is found in some significant phases like α, β, γ, δ, and κ having different band gap energies and shows varied optical properties. , Furthermore, the thermodynamic α-In 2 Se 3 phase evidently comprises two individual staking variants such as 2H and 3R phases. Both α­(3R) and α­(2H) In 2 Se 3 possess a three-layered rhombohedral structure accompanied by the space group R3̅m and a two-layered hexagonal structure having space group P6 3 . The α-In 2 Se 3 nanosheet reveals powerful covalent bonds along the planer lattice of the layered structure and weaker van der Waals interaction between adjacent layers, which shows enhanced carrier mobility.…”

Indium selenide has a narrow and tunable direct band gap, high absorption coefficient, broad response range, and high sensitivity.…”

Facile Synthesis of γ‐In2Se3 Nanoflowers toward High Performance Self‐Powered Broadband γ‐In2Se3/Si Heterojunction Photodiode

“…Up to now, several In 2 Se 3 nanostructures with different morphologies have been synthesized using ambient pressure and hydrothermal/solvothermal methods. Li et al presented an ambient pressure organic solution phase synthesis of amorphous In 2 Se 3 nanoparticles, flower‐like shaped β‐In 2 Se 3 nanocrystals, and 2D β‐In 2 Se 3 nanosheets . Wei et al reported the synthesis of porous γ‐In 2 Se 3 tetragons with a two‐step hydrothermal process .…”

In situ synthesis and improved photoelectric performances of a Sb2Se3/β-In2Se3 heterojunction composite with potential photocatalytic activity for methyl orange degradation

“…As an important semiconductor, indium selenide (In2Se3), has renewed interest in energy conversion and storage due to its narrow-gap, intrinsic n-type semiconductor and efficient visible-light absorption [17][18][19][20][21][22]. It is commonly held that In2Se3 is a complicated material, with several possible phases (α, β, γ, δ and κ phases) according to the temperature and material synthesis conditions [23][24][25][26].…”
