Terbium phosphide is aninorganic compound ofterbium andphosphorus with the chemical formula TbP.[1][2]
TbP can be obtained by the reaction of terbium andred phosphorus at 800–1000 °C:
The compound can also be obtained by the reaction ofsodium phosphide and anhydrousterbium chloride at 700~800 °C.[3]
TbP undergoes aphase transition at 40 GPa from aNaCl-structure to aCsCl-structure.[4] The compound can be sintered withzinc sulfide to make a green phosphor layer.[5]
TbP forms crystals of acubic system,space groupFm3m.[6]
The compound is asemiconductor used in high power, high frequency applications and inlaser diodes and otherphoto diodes.[1]
