White light emitting dysprosium doped CaS nanophosphors synthesized by solid state diffusion method

Ce3+ and Eu2+ activated BaAlSi5O2N7 phosphors have been prepared by the modified three step solid state diffusion method. Prepared phosphors are characterized by XRD, SEM, photoluminescence and thermoluminescence techniques. Upon excitation at 234nm, Ce3+ activated BaAlSi5O2N7 phosphor shows strong emission at 360nm. Upon excitation at 348nm, Eu2+ activated BaAlSi5O2N7 phosphor shows strong emission at 469nm in the blue region of the optical spectrum. After quenching at higher temperature and upon excitation at 363nm, BaAlSi5O2N7:Eu2+ phosphor shows broad band at 516nm in the green region of the optical spectrum. The trap parameters are studied using glow curve deconvolution. It was found that the obtained samples may be suitable for near UV excited white light emitting diodes.

Lighting Application

The polycrystalline NaLi2PO4:xEu (x=0.001,0.002,0.005,0.01 and 0.02) phosphors were successfully synthesized via modified solid state diffusion method [MSSDM]. The structural of prepared phosphor was confirmed by using XRD (X-ray diffraction) technique. Additionally, the photoluminescence (PL) behaviors of NaLi2PO4:xEu phosphor was studied.The XRD pattern of prepared phosphor is well matched with JCPDS file.The PL excitation of prepared phosphor was monitored at 618nm while emission was monitored at 393 nm. The effect of different concentrations of Eu3+ ions in NaLi2PO4 phosphor was studies and optimum PL intensity was obtained at x=0.005 mol. of Eu3+ ion. The CIE co-ordinates were calculated and obtained in orange- red region.
