The economic and technical use of terbium oxide is primarily due to its strong luminescent properties. It is mainly used as an activator in green phosphors for fluorescent lamps, LED displays, television screens, and monitors. Terbium oxide provides intense green light and improves color quality and brightness. Furthermore, 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 industry.

The following applications of terbium oxide are noteworthy:

• green phosphors for fluorescent lamps and LED lighting;
• color screens, televisions, and computer monitors;
• doping agent in laser materials and optical fibers;
• production of special glasses and optical filters;
• in phosphors and luminophores 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.
