首先要说明为什么氮化物晶体材料,GaN,InN,AlN以及他们的混合晶体是很重要的发光材料。由下面的禁带发光光谱(wavelength)和晶格(lattice)的图表可以看出,氮化物所覆盖的发光光谱范围是很宽的,是宽禁带的半导体材料,尤其是其混合晶体InGaN可以覆盖整个可见光光谱而AlGaN可以覆盖到深紫外光谱区,这在半导体光电材料中是具有突出...
The charge-induced degradation, defined byPi, is plotted against thede-h/rcvalues in Fig.4gfor Q1-Q7. It is worth mentioning that the variation trend ofPiwith QDs is consistent with that of EQE because both physical quantities eliminate the wavelength dependence. The results of Q1-Q5 are ex...
Riboflavin is maximally activated by BL of 450 nm, close to the peak of 460 nm, which was used in our study and is also prevalent in LEDs due to the low cost of manufacturing25. Since BL can degrade riboflavin into non-active photoproducts26, we speculate that BL could impair the...

(BM) had an annealed microstructure with equiaxed grains, while the weld zones contained martensite (α’) with large grains. The hardness increased in both regions, from around 123 HV to around 250 HV, in the heat-affected zone (HAZ) and fusion zone (FZ) areas. The tensile tests ...
colorpurity=(x−xi)2+(y−yi)2(xd−xi)2+(yd−yi)2where (x, y), (xi, yi), and (xd, yd) represent the coordinates, dominant wavelength of studied samples, and white illumination, respectively. For CPO:1.5%Bi3+, the color purity is as high as 98%, which is higher than ...
Exposure to short-wavelength light (415–465 nm, violet-blue) contributes to photoaging and skin hyperpigmentation in melanocompetent individuals [7,17]. The shorter the wavelength, the greater the contribution. It is assumed that exposure to light at a wavelength of above 480 nm will have no ...
Afterwards, 0.1 mL solution was taken and mixed with 0.4 mL of 5% (w/v) salicylic acid (in pure H2SO4) and 9.5 mL of 8% NaOH, finally the nitrate content was measured with TU-1810s spectrophotometer (PERSEE, Beijing, China) at a wavelength of 410 nm. Determination of vitamin C ...
