THE WHITE BIRDS
by: W.B. Yeats
would that we were, my beloved, white birds on the foam of the sea!
We tire of the flame of the meteor, before it can fade and flee;
And the flame of the blue star of twilight, hung low on the rim of the sky,
Has awakened in our hearts, my beloved, a sadness that may not die.
A weariness comes from those dreamers, dew-dabbled, the lily and rose;
Ah, dream not of them, my beloved, the flame of the meteor that goes,
Or the flame of the blue star that lingers hung low in the fall of the dew:
For I would we were changed to white birds on the wandering foam: I and you!
I am haunted by numberless islands, and many a Danaan shore,
Where Time would surely forget us, and Sorrow come near us no more;
Soon far from the rose and the lily, and fret of the flames would we be,
Were we only white birds, my beloved, buoyed out on the foam of the sea!

The White Birds
By W.B.Yeats
I would that we were, my beloved, white birds on the foam of the sea!
We tire of the flame of the meteor, before it can fade and flee;
And the flame of the blue star of twilight, hung low on the rim of the sky,
Has awaked in our hearts, my beloved, a sadness that may not die.
A weariness comes from those dreamers, dew-dabbled, the lily and rose;
Ah, dream not of them, my beloved, the flame of the meteor that goes,
Or the flame of the blue star that lingers hung low in the fall of the dew:
For I would we were changed to white birds on the wandering foam: I and you!
I am haunted by numberless islands, and many a Danaan shore,
Where Time would surely forget us, and Sorrow come near us no more;
Soon far from the rose and the lily and fret of the flames, would we be,
Were we only white birds, my beloved, buoyed out on the foam of the sea!

【南邮团队造出寿命长达4.2秒的高效蓝色余辉材料，在全彩显示和高级安全打印上具备应用潜力】
据史料记载，在史前炎帝、神农时，人们就已发现夜明珠。在春秋战国时代，人们把夜明珠称作“悬黎”和“垂棘之璧”，资料显示在当时只有身兼政治军事家和经济学家的范蠡、和另一位巨富巨富猗顿，买得起这种在黑暗中能自行发光的珠宝。宋元明时期，皇室尤其喜欢夜明珠，其中元朝曾派官员专门到斯里兰卡购买红宝石夜明珠和石榴石夜明珠。到了现代，许多盗墓题材的影视剧也常以夜明珠为创作素材。
在分类上，夜明珠可分别按照材质和磷光体做划分。其中，以磷光体来分类，它可被分为“长余辉蓄光型夜明珠”和“永久发光的夜明珠”。在“长余辉蓄光型夜明珠”中，由于磷光体中的激活剂不具备放射性，因此只能在被外界光源比如日光、紫外线等激发后才会发光。
最近，南京邮电大学材料科学与工程学院黄维院士团队的陶冶教授、和该校信息材料与纳米技术研究院陈润锋教授团队，以夜明珠为灵感开发出一款寿命长达 4.2 秒的高效蓝色余辉材料。审稿人称，此工作是对长余辉领域的另一突出贡献。借此开发出来的材料，可作为多彩型高级防伪墨水，通过喷墨打印技术可制备出颜色丰富的图案，在多重信息加密中具备应用能力。
4 月 15 日，相关论文以《通过磷光 FRET 按需调节水溶性聚合物的余辉颜色用于多色安全印刷》（On-demand modulating afterglow color of water-soluble polymers through phosphorescence FRET for multicolor security printing）为题，发表在 Science Advance 上。南京邮电大学黄维院士、陶冶教授和陈润锋教授，担任共同通讯作者。
