这项技术的关键在于三价铕离子([latex]Eu^{3+}[/latex])的电子结构。
The development by Levine and Palilla at GTE Laboratories was a landmark event. It solved the ‘red problem’ that had plagued the television industry for years. The brightness of the new red phosphor was so much greater than the existing green and blue phosphors that manufacturers actually had to reduce its concentration in the screen mixture to achieve a balanced white color. This innovation not only made color television commercially viable and appealing to the mass market but also spurred further research into other rare-earth phosphors for various applications, including lighting and lasers.
