  red light
Incubation of cells of the cyanobacterium Spirulina platensis under conditions of exposure to low-intensity (2-3 μE m-2 s-1) red light, which was predominantly absorbed by photosystem I (PS I), caused atypical adaptation changes.
      
Effect of Vernalization and Red Light Illumination of Seedlings of Bread Wheat (Triticum aestivum L.) on the Temperature Profile
      
We studied temperature dependence of phosphodiesterase activity in vernalized and unvernalized winter wheat on the one hand and in etiolated and red light illuminated seedlings of alternate wheat on the other hand.
      
Short-term experiments demonstrated that red light illumination is similar to long photoperiod by the effect on the long-day plants.
      
Changed temperature profile is a radical control mechanism of phosphodiesterase activity in response to the influences (red light and vernalizing temperatures) responsible for competence of various bread wheat forms for generative growth.

Cr 3+ ion doped YAG (Cr 3+ ∶YAG) layers grown by LPE is a newly developed single crystalline cathodoluminescent phosphor with a broad emission in red band. The maximum intensity of Cr 3+ emission in YAG is at λ max ≈689 nm, 709 nm with a color point of x=0 6551, y=0 2949, which is of the same chromaticity with a red emission of λ=638 nm. The abundant red components of Cr 3+ emission in the vicinity of λ≈700 nm give a deep impression, this made Cr 3+ ∶YAG of great...

CaSiO3∶(Pb,Mn) phosphor particles with red luminescence were prepared by aqueous co-deposition reaction. Surface modification of CaSiO3∶(Pb,Mn) phosphors was carried out by coating transparent conductive films of Al-doped zinc oxide which were formed by homogeneous phase co-precipitation and a heat treatment process. The coated phosphors were characterized by X-ray diffraction (XRD), photoluminescence (PL), transmission electron microscope(TEM), and conductance measurements. The results show that the conductivity...

CaSiO3∶(Pb,Mn) phosphor particles with red luminescence were prepared by aqueous co-deposition reaction. Surface modification of CaSiO3∶(Pb,Mn) phosphors was carried out by coating transparent conductive films of Al-doped zinc oxide which were formed by homogeneous phase co-precipitation and a heat treatment process. The coated phosphors were characterized by X-ray diffraction (XRD), photoluminescence (PL), transmission electron microscope(TEM), and conductance measurements. The results show that the conductivity of ZnO∶Al-coated phosphors at n(Zn)/n(Ca) = 10%, n(Al)/n(Zn) = 5% is improved obviously when the corresponding photoluminescence intensity is the same as the prepared phosphors. To lower the resistivity of phosphors, the experimental conditions are optimized, which include a hydrolyzing temperature of 75℃, hydrolyzing duration of 1.5 h, heat treat-ment temperature of 500 ℃ and heat treatment time of 45 min.

利用溶液中的共沉淀反应制备了CaSiO3∶(Pb,Mn)红色光致荧光粉。以Zn(NO3)2·6H2O和AlCl3·6H2O为原料,借助CO(NH2)2水解反应,用化学均相共沉淀法和热处理工艺在荧光粉表面包覆一层ZnO∶Al透明导电薄膜。对包覆前后的样品进行了X射线衍射结构分析、光致荧光分析、透射电镜形貌观察及电阻测量。结果显示:包覆后荧光粉的电导率显著提高,但光致荧光峰的位置和强度无明显变化。综合考虑包覆对荧光粉电阻率和荧光性质的影响,优化包覆条件和热处理条件为:n(Zn)/n(Ca)=10%,n(Al)/n(Zn)=5%,75℃水解1.5h;包覆后的样品在500℃热处理45min。
