Abstract

original image

A novel full-color-emitting phosphor composed of B, C, N, and O atoms is prepared by a one-step solution process from inexpensive precursors at ambient atmosphere and relatively low temperatures (below 900 °C). Emission from this novel phosphor can be tuned from the violet to the near-red, as illustrated in the figure, simply by varying the carbon content in the samples.
