Five types of phosphors for LED ribbon beam elements in white LED lamps have been studied. The phosphor composition and colorimetric parameters have been researched during the experiment. It is found that the larger and more uniform the grains of the phosphor, the higher the emission efficiency. The most similar in color to the white color coordinates of the sample No. 5 phosphor having also higher brightness compared with samples No. 1 – No. 4.

A series of Ba1.91-xSrxSiO4:Eu2+, Dy3+phosphors were synthesized by the high-temperature solid-state reaction. The structure of powder samples were characterized by X-ray powder diffraction. The photoluminescence emission and excitation spectra are also studied. It can be proved the formation of the solid solution of Ba1.91-xSrxSiO4:Eu2+, Dy3+ compounds, and the phosphors can be efficiently excited by UV-visible light from 300 to 480 nm. The as-synthesized Ba1.91-xSrxSiO4:Eu2+, Dy3+ phosphors are promising candidates applicable to near-UV and blue LEDs for solid-state lighting.
