چکیده

We focus on the development of new silicate phosphors for a white LED. In the europium doped silicate system, four LED phosphor candidates—Li2SrSiO4:Eu, Ba9Sc2Si6O24:Eu, Ca3Si2O7:Eu and Ba2MgSi2O7:Eu were found. Luminescent properties under near UV and visible excitation were investigated for the new Eu2+ doped LED silicate phosphors. These new phosphors have a relatively strong absorption band in a long wavelength region. key words: phosphor, silicate, white LED

Preparation, Characterization and Photoluminescence Properties of Ca1–xSrxS:Eu Red-emitting Phosphors for a White LED

A series of Ca1–xSrxS:Eu (x = 0.0, 0.2, 0.4, 0.6, 0.8, 1.0) phosphors were synthesized by solid-state reactions. The Ca1–xSrxS:Eu phosphors have a strong absorption at 455 nm, which corresponds to the emission wavelength of a blue LED. The emission peak of Ca1–xSrxS:Eu is blue shifted from 655 to 618 nm with increasing Sr content. The characteristics of Ca1–xSrxS:Eu phosphors make them suitable...

Structural and Optical Properties of Eu- Doped Silicate Phosphors: A Review

In the Nineteenth century the traditional sulphide based phosphor has improved greatly but they applied only in some commercial fields because the sulphide series phosphors are very poor stability. The long afterglow property and brightness is not good enough. That is the reason the researcher is trying to the research on the other phosphors. The researcher got the aluminate based phosphors at ...
