A gas sensor apparatus () comprising a gas inlet (); a first gas sensor (); a first gas flow path between the inlet and the gas sensor; a humidifier () disposed between the gas inlet and the gas sensor in the first gas flow path of the gas sensor apparatus; and a dehumidifier () disposed between the humidifier and the first gas sensor in the first gas flow path. The gas sensor apparatus may have more than one gas flow path. The gas sensor apparatus may contain more than one sensor. The gas sensor apparatus may contain one or more filters for filtering a target gas or a non-target gas. The gas sensor apparatus may be used in detection of ethylene and/or 1-methylcyclopropene.

Gas sensor

An organic light-emitting device () comprising an anode (); a cathode (); a light-emitting layer () between the anode and the cathode; a first hole-transporting layer (A) comprising a first conjugated hole-transporting polymer between the anode and the light-emitting layer; and a second hole-transporting layer (B) comprising a second conjugated hole-transporting polymer between the first hole-transporting layer and the light-emitting layer, wherein a lowest excited state energy level of the first hole-transporting polymer is lower than the lowest excited state energy of the second hole-transporting polymer.

Organic light emitting device

Provided are organic light-emitting devices having an anode; a cathode; a first light-emitting layer between the anode and the cathode, the first light-emitting layer having a fluorescent light-emitting material with a triplet excited state energy level Tand a triplet-triplet annihilation (TTA) promoter with a triplet excited state energy level T, wherein T; and a second light-emitting layer between the anode and the cathode and adjacent to the first light-emitting layer, the second light-emitting layer having a phosphorescent material with a triplet excited state energy level T, wherein T&#x3e;T.

Organic light-emitting device incorporating a triplet-triplet annihilation promoter and method of forming the same

A method of forming an optical device comprising the steps of: providing a substrate comprising a first electrode capable of injecting or accepting charge carriers of a first type; forming over the first electrode a first layer that is at least partially insoluble in a solvent by depositing a first semiconducting material that is free of cross-linkable vinyl or ethynyl groups and is, at the time of deposition, soluble in the solvent; forming a second layer in contact with the first layer and comprising a second semiconducting material by depositing a second semiconducting material from a solution in the solvent; and forming over the second layer a second electrode capable of injecting or accepting charge carriers of a second type wherein the first layer is rendered at least partially insoluble by one or more of heat, vacuum and ambient drying treatment following deposition of the first semiconducting material.
