Terbium oxide (Tb₄O₇) is a high-quality oxide of the rare earth metal terbium and is one of the important compounds of rare earths. It is a fine powder of dark brown to black-brown color. Terbium oxide impresses with its excellent luminescent and optical properties, high thermal stability, and good chemical resistance. It is insoluble in water but dissolves well in acids to form terbium salts.

The economic and technical use of terbium oxide is mainly based on its strong luminescent properties. It is primarily used as an activator in green phosphors for fluorescent lamps, LED displays, television screens, and monitors. Terbium oxide provides intense green light and significantly enhances color quality and brightness. Additionally, it is used in the production of special glasses, optical materials, ceramics, and as a dopant in lasers. This makes terbium oxide a valuable raw material for the lighting, display, and optics industries.

The following applications of terbium oxide are particularly noteworthy:

• green phosphors for fluorescent lamps and LED lighting;
• color screens, televisions, and computer monitors;
• dopant in laser materials and optical fibers;
• production of special glasses and optical filters;
• in phosphors and luminescent materials for displays;
• in ceramics and high-tech optical materials.

Terbium oxide is characterized by the following properties:

• dark brown to black-brown fine powder;
• strong green luminescence;
• high thermal stability (melting point approx. 2337–2350 °C);
• excellent optical and photoluminescent properties;
• insoluble in water, soluble in acids;
• high chemical resistance.
