Spherical, sub‐micrometer Y 2 O 3 : Eu 3+ phosphor particles have been synthesized by a homogenous solution method. These cubic Y 2 O 3 : Eu spherical phosphor particles (ca. 300 nm) will be ideal for FED devices as they can densely close‐pack in very small pixels on screens (as shown herein.). The pixels are approximately hexagonal in shape where the length of the hexagonal side is about 5μm. The particles manifest high luminous efficiency (better than a commercial sample) under low voltage electron beam excitation. It is also shown herein that these particles are useful in voltage ranges up to 5000 V and perform well at such voltages.
