摘要

在本文中，我们提出了一个建议，通过在黄色发射YAG:Ce磷光体复合物中添加绿色发射CaF2:Ce3+，Tb3+磷光体来改善7700K WLED的相关色温偏差（D-CCT）和流明输出。从研究结果来看，与非发绿光的CaF2:Ce3+、Tb3+荧光粉相比，D-CCT可以降低4倍以上，流明输出增加1.5倍以上。结果表明，绿色荧光粉CaF2:Ce3+，Tb3+可以成为提高WLED的D-CCT和流明输出的新建议。

Effect of Green-emitting CaF2:Ce3+,Tb3+ Phosphor Concentration on the Correlated Color Temperature Deviation and the Lumen Output of the 7700 K Conformal Packaging WLEDst

In this manuscript, we propose a recommendation for improving the correlated color temperature deviation (D-CCT) and the lumen output of 7700 K WLEDs by adding the green-emitting CaF2:Ce3+,Tb3+ phosphor into the yellow-emitting YAG:Ce phosphor compounding. From the research results, the D-CCT could decrease more than 4 times, and the lumen output increased more than 1,5 times in comparison with the non-green-emitting CaF2:Ce3+,Tb3+ phosphor case. The results show that green-emitting CaF2:Ce3+,Tb3+ phosphor could become a new recommendation for enhancing the D-CCT and the lumen output of WLEDs.

期刊介绍： International Journal of Automation and Smart Technology (AUSMT) is a peer-reviewed, open-access journal devoted to publishing research papers in the fields of automation and smart technology. Currently, the journal is abstracted in Scopus, INSPEC and DOAJ (Directory of Open Access Journals). The research areas of the journal include but are not limited to the fields of mechatronics, automation, ambient Intelligence, sensor networks, human-computer interfaces, and robotics. These technologies should be developed with the major purpose to increase the quality of life as well as to work towards environmental, economic and social sustainability for future generations. AUSMT endeavors to provide a worldwide forum for the dynamic exchange of ideas and findings from research of different disciplines from around the world. Also, AUSMT actively seeks to encourage interaction and cooperation between academia and industry along the fields of automation and smart technology. For the aforementioned purposes, AUSMT maps out 5 areas of interests. Each of them represents a pillar for better future life: - Intelligent Automation Technology. - Ambient Intelligence, Context Awareness, and Sensor Networks. - Human-Computer Interface. - Optomechatronic Modules and Systems. - Robotics, Intelligent Devices and Systems.
