光材料论文润色

  Warm white light emission, thermochromic property and long persistent luminescence derived from multi-sites of Eu2+/Eu3+ in host lattice

  Making a further insight into the structure-property relation of luminescent materials is not only in theory but also with reference value in developing more practical materials in this field. This paper reports a new luminescent material K 5 Y(P 2 O 7 ) 2 :Eu (KYP:Eu), in which the Eu 2+ dopants may occupy K + or Y 3+ sites. As a result, a warm white emission covering a wide range of 430–720 nm is generated at room temperature, in which the bands at 430–520 nm are due to Eu 2+ in K + sites and the bands at 530–720 nm are attributed to Eu 2+ in Y 3+ sites. Owing to the difference of Eu 2+ sensitivity at different sites, or the effects of co-existence of Eu 2+ and Eu 3+ , a position interchange between Eu 2+ and Eu 3+ happens at very low temperature (<175 K), which leads to the emission colors turning from dark blue, through blue-white and finally to white with increasing temperature from 10 to 450 K. Besides,

  一般而言,英文母语润色的速度一天约2000到3000字,熟练的润色专家可能速度更快。考虑到稿件提交到润色公司后,润色公司内部还会需要在客服、主编和润色专家之间来回流转,一般而言,一篇6000字的文章正常需要5天左右时间。

  对于很多时间敏感的作者来着5天时间显然太长了,很多润色公司也提供加急的服务,在加急状态下,6000字的论文可以在1-2天内容完成。然而大部分公司的加急服务是收费的,特别加急的文章有时候甚至费用翻倍。

  国内作者发表sci润色基本上是必不可少的,作者想给文章润色,大多是需要寻求专业机构的帮助的,少数作者可以自己进行润色修改,但大部分作者不具备这样的能力,机构润色就需要支付一定的润色费用了,这也是发表费用的一部分,机构不同,费用就不同,与文章的质量水平也有关系。
