GALLIUM SELENIDE

The Gallium selenide is an organic compound with the formula Ga₂Se₃. The IUPAC name of this chemical is digallium selenium(2-). With the CAS registry number 12024-24-7, it is also named as Digallium diselenide.

Preparation: this chemical is carried out by the reaction of GaMe₃ with trioctyl phosphine selenium (TOPSe) in a high temperature solution of trioctyl phosphine (TOP) and trioctyl phosphine oxide (TOPO).
GaMe₃ + P[(CH₂)₇CH₃]₃Se → GaSe

Uses of Gallium selenide: it is said to have potential for optical applications but the exploitation of this potential has been limited by the ability to readily grow single crystals Gallium selenide crystals show great promise as a nonlinear optical material and photoconductor. Non-linear optical materials are used in the frequency conversion of laser light. Frequency conversion involves the shifting of the wavelength of a monochromatic source of light, usually laser light, to a higher or lower wavelength of light that cannot be produced from a conventional laser source. One original problem with using gallium selenide in optics is that it is easily broken along cleavage lines and thus it can be hard to cut for practical application. It has been found, however, that doping the crystals with indium greatly enhances their structural strength and makes their application much more practical. There remain, however, difficulties with crystal growth that must be worked out before gallium selenide crystals may become more widely used in optics.
