چکیده
Silicates are important class of materials due to their applications in many diverse areas. They proved to be an effective materials for various processes and materials related to applied mineralogy including technical and medieval glasses, blast furnace linings and combustion ashes. This study reports the synthesis and luminescence of Eu, Ce, Dy and Sm activated K4CaSi3O9 and BaCa2Si3O9 phosphors. The luminescent characteristics of RE (RE 3+ = Eu, Ce, Dy and Sm) -doped K4CaSi3O9 and BaCa2Si3O9 compounds have been investigated for the first time in detail and may be application in the field of LED and display device.. X-ray powder diffraction measurements confirmed the cubic phase structure of titled compounds. Good characteristics luminescence is observed in all as-prepared samples. The obtained results may have the potential application in the NUV white light emitting diode. Keywords— Photoluminescence, Phosphors, light emitting diode

Blue Emission in Ce and Eu Activated Lithium Fluoro Borate Phosphors
Using a simple combustion process, rare earth doped novel compounds like fluorides LiBF4 and Li3BF6 can be prepared. Combustion synthesis furnishes a quick method for preparation of these phosphors. The prepared phosphors were characterized by the photoluminescence (PL) techniques. It is suggested that borofluoride based materials can be developed as low-cost phosphors. Formation of single phas...
متن کاملRed-emitting silicon quantum dot phosphors in warm white LEDs with excellent color rendering.
We demonstrate red-emitting silicon quantum dot (SiQD) phosphors as a low-cost and environment-friendly alternative to rare-earth element phosphors or CdSe quantum dots. After surface passivation, the SiQD-phosphors achieve high photoluminescence quantum yield = 51% with 365-nm excitation. The phosphors also have a peak photoluminescence wavelength at 630 nm and a full-width-at-half-maximum of ...

متن کاملStructural 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 ...
