Rare earth (RE) pentaborates, both α- and β-polymorphs, are good candidates for photoluminescent hosts suitable for various RE activators. Ce3+ acts not only as an activator itself, but also as a sensitizer to other rare earth activators, like in t

Mechanistic understanding on the electronic structure of α'-Ga2S3 unravel that the electrons in nonbonding 3pz orbitals of two-coordinated S2- anions are photoexcited to the adjacent σ-type antibonding orbitals (Ga-4s and S-3p) and migrate thereaft

Completed solid solutions of Y1-xEux[B6O9(OH)3] were prepared by boric acid flux method and the structure of Eu[B6O9(OH)3] was determined by single crystal X-ray diffraction (XRD). The successful cationic doping was supported by the linear change of

The current white light emitting diode (WLED) employs an InGaN chip together with the yellow phosphor Y3Al5O12:Ce3+, however it has a weakness of insufficient red component. In addition to traditional Eu2+ or Mn4+ based red phosphors, we propose that

A series of layered compounds InGaZn1-xCuxO4 (x = 0−1) were prepared by sol-gel method for the first time and characterized by powder X-ray diffraction (PXRD). All these solid solutions adopt LnFe2O4-type structure and crystallize in R-3m. With an

Searching efficient red phosphors under near-UV or blue light excitation is practically important to improve the current white light-emitting diodes (WLEDs). Eu2+ - and Mn4+ -based red phosphors have been extensively studied. Here we proposed that Eu

The purpose of this work is to develop a single-phase phosphor emitting white light under the excitation of near UV light, targeted at the possible application in white light emitting diodes. Our rationale is to employ a host containing noncentrosymm
