Alternative to rare earth extraction of new alloys as LED light source phosphors

LED is a type of light source that is currently favored on the market. It has better performance than traditional incandescent bulbs and has a longer service life. However, the phosphor of the white LED light source uses a rare earth element, and the main function is to emit a longer light wave from the LED chip, so that the bulb emits visible light of a full spectrum.

The mining and processing of rare earths is quite dangerous. At present, China is the only country in the world to provide a considerable number of countries, which has led to the rise in the price of rare earths. For this reason, the research team led by Prof. Jing Li from Rutgers University in New Jersey is the LED light. The source successfully found an alternative solution.


The research team has extracted a new alloy from a very cheap and abundant copper iodide that can replace the rare earth as a source of LED light. The most important thing is that this extraction method is relatively simple and cost-effective. In addition, by adjusting the color and intensity, it can adjust the white light that is warmer than the existing LED.

Business Tablet

A business tablet must have powerful business functions. At present, users use tablet products more for entertainment, and insufficient development of commercial value has become a major factor restricting the development of tablet computers. Many far-sighted terminal manufacturers have set their sights on the business tablet field.
Generally speaking, when business users choose tablet PC products, they still focus on "regular items" such as processor, battery, operating system, and built-in applications, especially office software applications, which are a good helper for business users.
First of all, there must be powerful office software such as customer management software, which can record customer data and related information anytime, anywhere. There is also a need for powerful marketing software, software marketing, reducing manual intervention, and one person can handle all the publicity and customer information.
