Highly luminous, thermally stable and moisture-resistant light-emitting materials derived from quadridentate ONNO-type ligands and a Group 10 metal were employed as emissive dopants in organic light-emitting devices. The dopants have molecular structures represented by the formula I and II: wherein .....

A luminous organic metal material is synthesized, and has stability enough for sublimation and vacuum deposition is electrically phosphorescent, and can be used for organic LEDs (OLEDs) because of its colour from organe to red, high efficiency and high brightness. This new-light emitting material of.....

A two-mode photonic crystal fiber includes a core of a substantially transparent core material. The core material has a core refractive index and a length, and has a core diameter. The fiber also includes a cladding region surrounding the length of core material. The cladding region has a first subs.....
