What is Indium Selenide Used for?
Gold is a high-quality hedge hedging tool, favored by investors. Especially in recent years, with the increasing instability of the world economy, gold has become one of the preferred asset allocations of investors because of its functions of hedging and fighting inflation.
Earlier, the worsening situation in Ukraine sent gold prices soaring to a two-year high of $2,070 an ounce. But gold, along with other commodities, fell back last week as conditions changed and bulls took profits, hitting a low of $1,895 an ounce. Rising gold prices may also have an impact on the Indium Selenide prices.
According to China Business News, Goldman Sachs raised its gold price forecast in early March, considering Asian buyers' gold consumption demand, investment demand and central bank gold purchase demand continue to rise. Three -, six - and 12-month targets were raised to $2,300, $2,500 and $2,500 an ounce, respectively, from $1,950, $2,050 and $2,150. The last time all three accelerated was in 2010-11 when gold prices rose nearly 70%.
The World Gold Council has also noted that global gold demand is at its highest level in nearly two years, which is linked to a recovery in consumption and consumer sentiment to combat inflation.
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.

At present, international supply chains were shocked, and logistics and transportation efficiency decreases. Geopolitical conflicts further aggravate uncertainties about the European and American economic recovery and the global commodity supply. For this reason, I assume the price of the Indium Selenide would not decrease significantly in the short term.
