Hup­pertz lab - Phos­pho­r­ma­te­ri­als for LED‘s

Phosphors for the ever growing LED-lighting sector are an highly important research field in the current research of solid state chemistry. Within this class of materials, europium-activated phases have emerged as a promising substance class for inorganic phosphors with some of them, such as β-SiAlON, RE₂Si₅N₈:Eu²⁺ (RE = Ca, Sr, Ba), and CaAlSiN₃:Eu²⁺, becoming standard phosphors in the industry. Recent developments, such as the discovery of SLA and SALON, also demonstrated that there is still much potential within this substance class and the number of Eu²⁺ based phosphors is still increasing. So, our research focus lies on the discovery and characterization of new phosphors for a potential application in LED's.
