报道了Eu3+， Tb3+和Tm3+共掺杂的有机-无机纳米结构杂化体的发射色度从红色到绿色的微调。将温度从200 K提高到300 K，颜色坐标从色度图的1黄绿色区域平滑地转向红色。这是讨论热激活的能量转移机制，从Tb3+的能量状态到杂化的发射水平。
A fine-tuning of the emission chromaticity from red to green is, reported for organic-inorganic nanostructured hybrids co-doped with Eu3+, Tb3+, and Tm3+. Raising the temperature from 200 to 300 K changes the color coordinates smoothly from the 1 yellowish-green region of the chromaticity diagram towards the red. This is discussed in terms of thermally activated energy-transfer mechanisms from Tb3+ energy states to the hybrid's emitting levels.
