Popis:	With more and more research efforts being focused on phosphors for LEDs, new systems are constantly being explored. One such system is the ABPO4:Eu2+ with A = Li, Na and K and where B = Ca, Sr, and Ba. These phosphors will produce varying blue emissions from 400 nm out to around 480 nm upon excitation by UV emitting LED sources. In this study we have explored nine different phosphors having different combinations of A and B. The spectroscopic properties of these phosphors, as well as their external quantum efficiencies, and their temperature dependant lifetimes will be discussed.
