The discovery that europium-doped yttrium vanadate ([latex]YVO_4:Eu^{3+}[/latex]) could act as a brilliant red phosphor was a critical breakthrough for color television. Before this, red phosphors were weak, resulting in dull colors. The intense, narrow-band red emission from the [latex]Eu^{3+}[/latex] ion allowed for bright, vibrant color displays, dramatically improving the quality of color TV and setting the standard for display technology.
