Sr2LiAlO4 – A novel earth-abundant phosphor with excellent color quality

Posted on

Our paper on “Mining Unexplored Chemistries for Phosphors for High-Color-Quality White-Light-Emitting Diodes” has been published in Joule. Using supercomputers and data mining, we identified Sr2LiAlO4, the first known Sr-Li-Al-O quaternary crystal, as a highly promising phosphor material in low-cost, high-color-quality white LEDs. Eu2+ and Ce3+-activated Sr2LiAlO4 phosphors exhibit broad green-yellow and blue emissions, respectively, with excellent thermal quenching resistance of > 88% intensity at 150oC. A prototype phosphor-converted white LED utilizing Sr2LiAlO4-based phosphors yields an excellent color rendering index exceeding 90. This work is a collaboration between the Materials Virtual Lab (UCSD), McKittrick group (UCSD) and Im group (Chonnam University). The lead authors are Zhenbin Wang, Jungmin Ha and Yoon Hwa Kim. More information about this work can be found in the Jacobs School of Engineering News as well as Science Daily, Phys.org, etc.

matgenb – Getting data from the Materials Project

Posted on

The Materials Virtual Lab has started matgenb, a new public repository to share example notebooks that demonstrate the utilization of open-source codes for the study of materials science. We frequently get requests (from students, postdocs, collaborators, or just general users) for example codes that demonstrate various capabilities in the open-source software we maintain and contribute to, such as the Materials Project software stack comprising pymatgen, custodian, and Fireworks. This repo is a start at building a more sustainable path towards sharing of code examples. The first example notebook has been posted on Getting data from the Materials Project.

2016 year-end message by Prof Ong

Posted on

2016 is coming to a close. Before some of you leave for the holidays, I would like to wish you all a Merry Christmas. This year, I have decided to start a new tradition – the year-end message. It has been a great year for the Materials Virtual Lab. We have come a long way since our founding a little over three years ago, and I believe we have now firmly established ourselves as one of the up-and-coming computational materials research groups in the world. We will end 2016 on a high note with a little over 20 publications in highly respected journals. Funding is at a very healthy level for a group of our age, and we are now a dynamic family of three postdoctoral associates, ten graduate students and three undergraduates. Two of our earliest members (Zhi and Paul) have completed their Senate Exams, and another two (Chen, Zhenbin and Zhuoying) have completed their Literature Review Exams. We welcomed three new group members (Chi, Hui and Zhuonan), and one new-old group member (Richard) in Fall 2016. We will also soon say goodbye to Bala, who has found an excellent opportunity in NASA. We wish him all the best […]
