Uses

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 [Large single crystals of gallium selenide: growing, doping by In and characterization, Valeriy G. Voevodin,Olga V. Voevodinaa, Svetlana A. Bereznayaa, Zoya V. Korotchenkoa, Aleksander N. Morozova, Sergey Yu. Sarkisova, Nils C. Fernelius and Jonathan T.
