Blue light isclose to ultraviolet light in wavelength. Ultraviolet light is particularly damaging to tissue such as that in the retina, which is highly reactive to light, and some believe blue light may be damaging as well. Because of this, your retina can be prone to damagingoxidative stress....
Which one is the wavelength range of blue light? A.500-600 nm B.300-400 nm C.400-500 nm D.600-700 nm 点击查看答案进入小程序搜题 你可能喜欢 对侧疏忽综合征患者的注意出现哪些异常? A、对脑损伤侧线索过度注意 B、对脑损伤侧线索注意困难 C、对脑损伤对侧目标注意困难 D、对脑损伤对侧目标过...
and wide color gamut, wherein the emerging perovskite light-emitting diode (PeLED) rises in good response to these features, arousing more research passion on three primary-color PeLED devices1,2,3,4,5,6. Rapid progress has been made in red and green devices in the current stage7,8, whil...
Blue light (BL) is becoming increasingly prevalent in our environment raising concerns about its safety1,2. In fact, research on cells and model organisms suggests that BL may have a range of detrimental effects. A single acute blue light exposure causes photoreceptor death in the retina of mic...
After reduction of the independent variables, the possible recipes of the mixed white light with five monochromatic LEDs were numerated in the certain wavelength range. The BLHER of the practical mixed white light is always less than 0.06 when its correlated color temperature (CCT) changes from ...
PROBLEM TO BE SOLVED: To provide a luminous device which can efficiently emit light of optional color tone by converting white light from a light emitting diode to light of another wavelength and which has a simple structure and can be manufactured in high yield.田崎 益次...
Blue light below 453 nm has been also described to induce oxidative stress in a range equivalent to just 25% of that caused by UVA irradiation [8]. The fact that we are increasingly exposed to artificial blue light from electronic devices and indoor lighting (mostly LED) led us to wonder ...
根据第二段中“According to their study, retinal (网膜的) cells of the eye are sensitive to this blue light and directly convey information to areas of the brain that control appetite.(根据他们的研究,眼睛的视网膜细胞对这种蓝光很敏感,并直接将信息传递给控制食欲的大脑区域)”可知,根据研究显示,夜间...
474 nm) of 47 h (see Fig.1band Supplementary Fig.5b), close to the best results reported so far despite shorter emission wavelength11,14. To study the charge-induced degradation, we simultaneously monitor the EL and PL as a function of device operation time7,16. As seen in Fig.1...
In theory, the accessible wavelength range for InxGa1 − xN alloys spans from 365 nm (GaN) to 1771 nm (InN), providing coverage of the entire visible spectrum. However, beyond ∼480 nm the material quality of MOCVD-grown InxGa1 − xN declines continuously due to a variety of ...
