High-Brightness LaPO^sub 4^:Ce^sup 3+^, Tb^sup 3+^ Nanophosphors: Reductive Hydrothermal Synthesis and Photoluminescent Properties

This paper definitely reveals that ... (LAP) nanophosphors prepared by normal hydrothermal method suffer significant loss of luminescence due to the oxidation of ... at hydrothermal stage. To effectively protect ... from oxidation, a reductive hydrothermal process using hydrazine hydrate as a protecting agent is proposed to synthesize LAP nanophosphors with different ... and ... concentrations, which exhibited much stronger green photoluminescence (PL) and longer lifetime than the products prepared by normal hydrothermal method. Furthermore, the high-brightness LAP nanophosphors exhibited high-quenching concentration of ... the ... nanophosphor showed almost the same PL intensity as that of the commercially used ... bulk powder.
