ION EXCHANGE-ASSISTED SURFACE PASSIVATION TOWARD HIGHLY STABLE RED-EMITTING FLUORIDE PHOSPHORS FOR LIGHT-EMITTING DIODES

Ion exchange-assisted surface passivation toward highly stable red-emitting fluoride phosphors for light-emitting diodes

Abstract A facile and environmentally friendly ion exchange-assisted surface passivation (IASP) strategy is presented for synthesizing red emitting Mn4+-activated fluoride phosphors.A substantial, pristine Mn4+-free shell layer, applied as a coating to Mn4+ doped potassium fluorosilicate K2SiF6:Mn4+ (KSFM) phosphors, enhances both water resistance

Assessing the Use of Artificial Hibernacula by the Great Crested Newt (Triturus cristatus) and Smooth Newt (Lissotriton vulgaris) in Cold Climate in Southeast Norway

Construction of artificial overwintering habitats, hibernacula, or newt hotels, is an important mitigation measure for newt populations in urban and agricultural areas.We have michael harris ii headband monitored the use of four artificial hotels built in September 2011 close to a 6000 m2 breeding pond in Norway.The four hotels ranged from 1.6 to 1
