Synthesis of new phosphors for LEDs

For several years, part of the Huppertz working group at the University of Innsbruck has been working on the synthesis of new phosphors via solid-state synthesis, which is carried out both under normal pressure and under extreme high-pressure conditions (up to 150,000 bar). The lecture gives an introduction to the basic working techniques, followed by the presentation of current research results from the last few years in the fields of alkali lithosilicates and oxonitridosilicates, such as the new narrow-band red phosphor SrAl2Li2O2N2:Eu2+ (SALON) and its disordered variants SrAl2−xLi2+xO2 +2xN2−2x (x = 0.12 and 0.66).
