What is Indium Selenide Used for?
Risk aversion plunged on the positive news of the Russia-Ukraine talks. After several days of rising oil prices, the price of precious metals continued to fall. Domestic futures markets remain stable for the time being.
Back in international markets, WTI crude futures briefly dipped below $100 a barrel, while Brent crude hit its lowest intraday level in nearly two weeks. Spot gold briefly fell below $1,900 an ounce. Comex gold futures closed down 1.1 percent at $1,918.4 an ounce. Comex silver futures closed down 1.14 percent at $24.91 an ounce. "Recently, crude oil prices have been extremely sensitive to changes in geopolitical news." Traders believe that the current oil price is still in the broad impact, Ukraine will still be a premium in the case, although the market further decline, but should not be too pessimistic, it is recommended to wait and see for the time being. The Ukrainian premium is still there and there will be some volatility in the Indium Selenide market.
What is Indium Selenide?
Indium Selenide is an inorganic compound with the chemical formula In2Se3.
Black crystals or dark black scale-like substances. It is a typical
two-dimensional layered semiconductor material.
Single crystal indium selenide can be prepared by the Bridgman–Stockberger
method. Using a certain proportion of selenium and indium as raw materials, each
compound of indium selenide can be prepared by reacting in a tube furnace at
high temperature for a long time.
The research on the hydrothermal synthesis of In2Se3 was relatively late.
Ascorbic acid was dissolved in ethanol solution at 60 °C, then InCl3 and Se
powder were added, and the reaction kettle was kept at 220 °C for 20 hours. -4

What is indium selenide used for
InSe is a bandgap-tunable layered semiconductor material with nonlinear
optical response over a wide wavelength range. The researchers obtained InSe
nanosheets with suitable thickness and band gap by a liquid-phase exfoliation
method, and systematically investigated their nonlinear optics and ultrafast
carrier dynamics at different pulse width scales (ns and fs).
The researchers found that InSe nanosheets are more likely to reach saturable
absorption under wide-pulse laser excitation. Furthermore, the InSe dispersions
exhibit different mechanisms of scattering phenomena at different pulse
durations, which are due to the thermal effect under ns-pulse excitation and the
dynamic spatial self-phase modulation of the laser flow under fs-pulse
At the same time, the optical switch modulation is realized by
utilizing the competitive relationship between saturable absorption at low
energy and nonlinear scattering at high energy. The time-resolved pump-probe
results indicate that the InSe dispersion has an ultrafast saturable absorption
process and a photoinduced absorption process that may be caused by free carrier
absorption or bandgap renormalization.

The war in Russia and Ukraine is roiling global financial markets. Russia and Ukraine are important commodity suppliers in the world, so their conflict is bound to make a full impact on the global commodity supply. In view of this, the price of the Indium Selenide may continue to rise in the future.
