多孔硅的室温全彩色光致发光是通过电化学腐蚀辅助的氧化性金属，如锌，没有任何postanodizing处理。通过简单地将阳极氧化电流密度从20 mA/cm 2改变到100 mA/cm 2，可以将发射调谐到可见光范围内的任何波长。发光强度足够高，所有颜色都是肉眼可见的。老化行为的红色，绿色和蓝色的光致发光也超过三个月的时间跨度进行了研究。虽然峰值波长的钉扎对于所有峰值都随着老化在一定水平下发生，但是无论初始发射是绿色还是蓝色，蓝色发射总是钉扎在420 nm左右。
Ambient full-color photoluminescence from porous silicon has been realized through electrochemical etching aided by an oxidative metal such as Zn without any postanodizing treatment. The emission can be tuned to any wavelength in the visible range by simply changing anodizing current density from 20 to 100 mA/cm 2 . The luminescence intensity is high enough that all colors are visible to naked eyes. Aging behavior of the red, green, and blue photoluminesence is also investigated over a three-month time span. While the pinning of the peak wavelength occurs with aging at a certain level for all the peaks, the blue emission always gets pinned at around 420 nm whether the initial emission is green or blue.
