Synthesis and Photoluminescence Study of Bi3+ and Pb2+ Activated Ca3(BO3)‎2

Abstract EN

The photoluminescence properties of Pb2+ and Bi3+ doped Ca3(BO3)2 prepared by solution combustion synthesis technique are discussed.

The structure of the prepared phosphor is characterized and conformed by XRD and FTIR.

SEM images of the prepared materials show irregular grains with agglomerate phenomena.

Prepared phosphors achieved the band emissions, respectively, at 365 nm and 335 nm corresponding to the transition P1→S013.

Optimum concentration, critical transfer distance, and Stokes shift of the synthesized materials were measured.

These phosphors may provide an efficient kind of luminescent materials for various applications in medical and industry.
