Abstract:
In the last decade, an immense progress has been made in white LEDs, mainly
due to the development of red-emitting phosphors. In this paper, we report
on the synthesis of Eu3+ activated Y2MoO6 by a self-initiated and
self-sustained method. The obtained powder was calcined at various
temperatures in the 600-1400?C range and examined by X-ray diffraction
(XRD), scanning electron microscopy (SEM), transmission electron microscopy
(TEM) and photoluminescence spectroscopy (PL). The results revealed that all
powders are single phase Y2MoO6:Eu3+, with particle size in the nanorange at
lower treatment temperatures (600 and 800?C) and in the microrange at
higher calcination temperatures (1000-1400?C). The obtained powders are
promising materials for white light-emitting diodes as they can efficiently
absorb energy in 324-425 nm region (near-UV to blue light region) and emit
at 611 nm in the red region of the spectrum, while exhibiting high thermal
and chemical stability.
