The possibility of a modified Jones reductor that can be used to reduce Europium (Eu) for the purpose of doping in thermally unstable host lattice in solution was investigated. A modified Jones reductor which can be used to reduce Eu³+ to Eu2+ and doping same into thermally unstable host lattice was constructed. It was then used to reduce Europium in solution. The reduced Europium was analysed by measuring its emission using Fluorolg-3 spectrofluorometer. The constructed Jones reductor consisted of a column (13cm x 2.5cm), a receiver with a neck of about 2.5cm, an adaptor of diameter NS14.5cm and three taps of 2.5cm each for the exits. A solution of prepared Europium salt was passed through the modified Jones reductor to reduce Eu³+ to Eu2+. The result showed that within the limit of error almost 99% reduction was achieved. In conclusion, the modified Jones reductor can be used to reduced Europium and dope it into compounds that are difficult to dope through the melt method.
