Effect of LiCl on the Microstructure and Luminescence Properties of YVO4:Eu3+ and YBO3:Eu3+ Phosphors
In this investigation, Eu3+ doped YVO4 /YBO3 phosphors were synthesized individually by conventional solid state method at 1100 °C under atmosphere condition. Meanwhile, different amounts of LiClwere used as the flux compound to modify the morphology of the phosphor particles and also final luminescence properties. It was concluded that even small amounts of fluxes play a vital role in the grow...
متن کاملConversion of Biowaste Asian Hard Clam (Meretrix lusoria) Shells into White-Emitting Phosphors for Use in Neutral White LEDs
The increasing volume and complexity of waste associated with the modern economy poses a serious risk to ecosystems and human health. However, the remanufacturing and recycling of waste into usable products can lead to substantial resource savings. In the present study, clam shell waste was first transformed into pure and well-crystallized single-phase white light-emitting phosphor Ca₉Gd(PO₄)₇:...
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 کاملLight Converting Inorganic Phosphors for White Light-Emitting Diodes
White light-emitting diodes (WLEDs) have matched the emission efficiency of florescent lights and will rapidly spread as light source for homes and offices in the next 5 to 10 years. WLEDs provide a light element having a semiconductor light emitting layer (blue or near-ultraviolet (nUV) LEDs) and photoluminescence phosphors. These solidstate LED lamps, rather than organic light emitting diode ...
متن کاملStudy structural and up-conversion luminescence properties of polyvinyl alcohol/CaF2:erbium nanofibers for potential medical applications
Objective(s): This paper describes synthesisPolyvinyl Alcohol/CaF2:Er nanofibers because of its photoluminescence properties.Materials and Methods: First, CaF2:Er nanocomposite synthesized with co-precipitation method. In order to prepare polyvinyl alcohol (PVA)/CaF2:Er nanofibers, CaF2:Er nanocomposites were added to the polyvinyl alcohol (PVA) polymer. PVA/CaF2:Er composite nanofibers were...
