Luminescence and luminescence quenching of K2Bi(PO4)(MoO4):Sm3+ phosphors for horticultural and general lighting applications

Popis výsledku v původním jazyce

The purpose of this study is to investigate the optical properties of Sm3+ doped K2Bi(PO4)(MoO4) phosphors as possible candidates for application in light emitting diodes for horticultural and general lighting applications. Sm3+ doped phosphors with 0.5-100 Sm3+ have been prepared by solid state reaction method. The synthesized materials were investigated by X-ray diffraction and scanning electron microscopy. The room temperature reflection, excitation, and emission spectra, photoluminescence decay curves, as well as temperature dependent emission and excitation spectra and PL decay curves were measured and discussed. Moreover, quantum efficiencies, and lumen equivalents were determined and discussed. The prepared K2Bi(PO4)(MoO4):Sm3+ phosphor samples show moderate quantum efficiency, high colour purity, and a high quenching temperature. These properties are required for phosphors if they are under consideration for application in LEDs and other areas.
