New synthesis technology for high efficiency Eu:YV1-x P xO4 nanophosphor

Abstract

Highly efficient Eu:YV1-xPxO4 phosphor particles, ̃200nm in size, were synthesized using a new synthesis technique. The resulting particles exhibited higher photoluminescence efficiency than the micron-sized commercial sample, highlighting their high quality. To the best of our knowledge, such high efficiency has not been achieved without a surface and heat treatments. In addition to the photoluminescence spectrum, high resolution transmission electron microscopy (HRTEM) demonstrated perfect crystallinity with clear lattice fringes. © 2010 The Ceramic Society of Japan.
