Abstract

The synthesis of nanosized phosphors by using the non-thermal plasma-driven method is presented. The method allows to control the average grain size of nanocrystals. The synthesis of Eu3+-doped Y2O3 nanocrystalline phosphors at water solution of nitrates is described. The average sizes of nanocrystals were controlled by sintering temperature. Their structure, morphology, and luminescent properties were investigated.

Highlights

The Eu3?-doped yttria (Y2O3) is one of the most popular red phosphors commonly applied in different light-emitting devices (Hunt and Chakhovskoi 1997; Shea 1998)
Despite the above-mentioned methods (Hreniak et al 2004; Lee and Choi 2005; Pechini 1967; Xu et al 2005; Song et al 2003) and the others presented elsewhere (Barta et al 2010; Chen et al 2005; Cuba et al 2010a, b, 2011, 2012; Gbur et al 2011; Jang et al 2006; Tang et al 2003; Vollath and Szabo 2006; Zhang et al 2004) synthesis of nanocrystals using only water solutions of nitrates exposited for non-thermal plasma (NTP) is possible
It should be emphasized that only the water solutions of yttrium nitride and europium nitride were used as a substrate of the reaction
