Researchers used a Sol-gel technique to create a special type of phosphor that emits white light. They studied its structure using X-ray diffraction and found it to be crystalline. The phosphor was also analyzed using infrared spectroscopy and electron microscopy to understand its properties. When tested for light emission, the phosphor showed three different colors of light at the same time, resulting in white light. This suggests that the phosphor could be used in energy-efficient lighting applications.
