Thus, the compounds 1 and 2 can have greater use to serve as light-absorbing materials at a visible light band in photoelectric functional material.

这说明化合物1和2在光电功能材料中作为可见光波段的吸光材料将有较大的用途。

The light that we see with our human eyes as a band of rainbow color falls in the range of what's called visible light.

我们用肉眼看到的彩虹色的光属于可见光。

Visible light consists of different colors or wavelengths, which together make up what's called spectrum, a band of colors, like you see in a rainbow.

可见光由不同的颜色或波长组成，它们共同组成了所谓的光谱（一段颜色），就像你在彩虹中看到的那样。

These are photodetectors, band gap two electron volts, respond to visible light.

这是光电探测器，能带隙为2电子伏，当它反应于可见光。

It arises from light waves in the visible band of the electromagnetic spectrum, the segment with wavelengths of 400 billionths of a metre at the blue end to 700 billionths at the red.

At the moment, it affects visible light but a small amount of tweaking should produce a band gap at a wavelength of 1.5 microns (millionths of a metre).
