In this article, we have discussed about the significance of bismuth as host in the development of LEDs . As a result of the growing usage of phosphors in LEDs, the term "phosphor-converted LEDs" was coined (pc-LEDs). This manuscript provides a full description of the various bismuth phosphors with different doping and there emission spectra in photoluminescence studies. the increasing use of phosphors in LEDs has led to the development of pc-LEDs, which have numerous applications in various industries. The synthesis of phosphors for pc-LEDs involves several methods, and the materials used in their fabrication are critical in determining the performance of the pc-LED. Ongoing research in the field of phosphors and pc-LEDs is expected to lead to the development of more efficient and cost-effective lighting solutions.
