Project Report from the year 2015 in the subject Physics - Optics, ST Anne's College Of Engineering And Technology (St. Anne's College of Engineering and Technology, Panruti, Tamilnadu, India), language: English, abstract: Trivalent rare-earth-ion-activated molybdate based phosphors have attracted great attention for solid-state lighting applications by virtue of their long lifetimes, and efficient luminescence property. The rare-earth ions are represented by a partly filled 4f shell that is completely shielded by 5s2 and 5p6 orbitals. Therefore, emission transitions provide sharp intense...
