Effect of Cr³⁺ doping on structural and optical properties of Eu³⁺ doped LaVO₄ phosphor

Abstract

The Eu3+, Cr3+ co-doped LaVO4 phosphor gives red (614 nm) and NIR (700 nm) emissions due to Eu3+ and Cr3+ ions, respectively. The decrease in PL intensity of the Eu3+ doped LaVO4 phosphor is due to energy transfer from Eu3+ to Cr3+ ions.

“…These luminescent materials nd applications in various elds, e.g., sensors, solar cells, plant growth, display, lighting, biophotonic applications, and anti-counterfeiting. [1][2][3][4][5][6][7] Usually, rare earth ions such as Eu 3+ , Tb 3+ , Sm 3+ , and Dy 3+ ions are widely used in lighting applications. However, there are some limitations of using these rare earths as dopants in luminescent materials.…”

“…Because it often also produces strong orange at 590 nm, week deep red around 650 nm, and deep red at 700 nm, the radiation that is released is a mixed red. It can also generate white light [red, green, blue (RGB)], whereas other rare-earth elements create blue and green light instead [1][2][3][4].…”
