Photoluminescence properties of Al3GdB4O12:Eu phosphors
An investigation is reported of the photoluminescence (PL) properties of Al3GdB4O12:Eu phosphors. Under vacuum ultraviolet excitation, Al3GdB4O12:Eu exhibited a bright red luminescence with CIE chromaticity coordinates of (0.643, 0.356) with a PL intensity of 60% of the sodium salicylate standard. The PL spectrum showed a ground state splitting pattern consistent with D3 symmetry. The PL excita...
متن کاملPreparation, 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...
متن کاملEnhanced Photoluminescence Properties of Li/Al-doped YPO4:Eu Phosphors
Different concentrations of Li/Al-doped YPO4:Eu0.05 phosphors have been prepared by the solid state reaction method and are characterized by X-ray diffraction, scanning electron microscopy, excitation and emission measurements. The dependence of various optical and morphological properties of the prepared materials on Li/Al concentration has been discussed in our present work. Incorporation of ...

متن کاملdetermination of some physical and mechanical properties red bean
چکیده: در این تحقیق، برخی خواص فیزیکی و مکانیکی لوبیا قرمز به-صورت تابعی از محتوی رطوبت بررسی شد. نتایج نشان داد که رطوبت بر خواص فیزیکی لوبیا قرمز شامل طول، عرض، ضخامت، قطر متوسط هندسی، قطر متوسط حسابی، سطح تصویر شده، حجم، چگالی توده، تخلخل، وزن هزار دانه و زاویه ی استقرار استاتیکی در سطح احتمال 1 درصد اثر معنی داری دارد. به طوری که با افزایش رطوبت از 54/7 به 12 درصد بر پایه خشک طول، عرض، ضخام...
