Quenching Study on Iron Impurity in Eu2+, Dy3+ Doped Strontium Aluminate Phosphor Prepared by Nano-Coating Process杨雪峰,宁桂玲,刘杰,潘文,林源摘 要:A series of long... that the precursor particles had nanometer size distribution. The optical quenching of iron impurity on the phosphor powders were investigated by X-Ray powder Diffraction (XRD) and photoluminescence......
. The results show that the interdiffusion coefficients depend strongly on the concentration. These coefficients are compared with the impurity diffusion coefficients which are determined by Vignes-Birchenall... diffusion couple; interdiffusion; impurity diffusion; activation energy; frequency factor ......
), which is strong acid-resistance to HF. Unlike HF,the chemical stripping-off effect of the particle size of silicon powder made by aqua regia decreases obviously and the impurity phases easily expose at the grain boundaries. The loss rates of Si powder after two acids are less than 3.5%. Key words: metallurgical silicon; acid leaching; purification process; impurity phases 太阳能光伏发电产业因其取之不尽,用之不竭,清洁环保和安......
