Products in Battery & Electronic Materials: Yttrium Compounds

Yttrium Aluminum Garnet (YAG) LED Phosphor is efficient and suitable for creating high correlated color temperature (CCT). YAG phosphor is very stable due to its unique crystal structure and its synthetic route is very straightforward. It can be effectively excited by a 450nm blue LED chip with an emission peak wavelength in the 530-560nm range. YAG phosphor exhibits yellow-light emission from the characteristic 5d and 4f energy levels. The energy levels of the 5d1 excited states and the emission photon energy of Ce3+ ion strongly depend on the host crystals via the crystal-field-induced energy level splitting of the 5d1 orbital. Combined with a blue InGaN LED, YAG phosphor has been successfully used in WLED.

Yttrium Gallium Aluminum Garnet (YGaAG) LED Phosphor addition shifts the peak emission wavelength to short wavelengths, therefore giving the phosphor a stronger green component when compared with Yttrium Aluminum Garnet (YAG) LED Phosphor. This allows the new white LED to have a variety of color temperature including daylight white (5000~6500K) as well as incandescent-like white (2500~3300 K).

Nexceris Yttria-Stabilized Zirconia (8 mole %) - Nanopowder is a commonly used and well-characterized ceramic electrolyte material. This nanoscale grade of YSZ-8 powder (with crystallite size of 5 - 10 nm and surface area of > 100 m2/gram) is offered for use as a sintering aid or as an activity-enhancing additive in composite cathodes and cermet anodes. As provided, the nanoscale YSZ-8 powder is agglomerated and needs to be further processed in order for optimum dispersion.
