A novel laminate is provided to improve the operating stability of thioaluminate based phosphors used in ac thick film dielectric electroluminescent displays. The novel structure comprises a rare earth activated alkaline earth thioaluminate phosphor thin film layer and an aluminum oxide or aluminum oxynitride layer provided directly adjacent and in contact with the bottom of the phosphor thin film layer. The invention is particularly applicable to phosphors used in electroluminescent displays that employ thick dielectric layers subject to high processing temperatures to form and activate the phosphor films.

A method is obtained of manufacturing a semiconductor device including a semiconductor layer with high field-effect mobility. According to the semiconductor device manufacturing method, a semiconductor layer is formed on a substrate and then the semiconductor layer is irradiated with high energy beam. Then, a heat treatment is provided under a temperature condition capable of reducing the surface roughness of the semiconductor layer. The radiation of high energy beam toward the semiconductor layer improves the crystalinity of the semiconductor layer and the subsequent heat treatment reduces the surface roughness of the semiconductor layer to enhance the field-effect mobility of the semiconductor layer.

In order to reduce the side effects of paclitaxel derivatives having excellent anti-cancer effects, an attempt was made to produce a liposome encapsulating paclitaxel derivatives such as paclitaxel monoglycosides and docetaxel monoglycosides. However, the introduction efficiency of paclitaxel derivatives, etc., into a liposome was poor, and this technique was not developed to a practical level. The present invention provides a method for producing a liposome encapsulating a paclitaxel monoglycoside and/or a docetaxel monoglycoside, and having an antibody specifically recognizing a cancer cell, the method comprising a step of bringing a liposome encapsulating a polyoxyethylene ester derivative, a lower alcohol, and a buffer or water into contact with a solution in which a paclitaxel monoglycoside and/or a docetaxel monoglycoside is dissolved in an alkylene glycol-containing buffer or water.

An extended area uniform light source providing uniform luminance is taught for displays and other applications where the light emission can be planar or have curvature. The uniform light source is achieved using a combination of a blue light-emitting electroluminescent layer and a highly stable inorganic photoluminescent colour conversion layer to tailor the colour spectrum of the emitted light. The invention thus encompasses the uniform light source, displays incorporating the uniform light sources as well of methods of making such light sources and displays.

A thin film phosphor for an electroluminescent device, the phosphor being selected from the group consisting of thioaluminates, thiogallates and thioindates having at least one cation selected from elements of Groups IIA and IIB of the Periodic Table of Elements. The phosphor being activated by a rare earth metal and containing oxygen as a partial substitute for a portion of the sulphur in the crystal lattice of the thiogallate, thioindate or thioaluminate. The phosphor is a single phase homogeneous compound and provides improved luminance stability. An electroluminescent device comprising the thin film phosphor is also described and methods of making the phosphor of the invention.

摘要:
A compact antenna comprises a core which is a hard linear member having a predetermined shape corresponding to resonance characteristic, a conductor film which covers at least a portion of an outer surface of the core and which has higher electric conductivity than that of the core, and a substrate which closely surrounds and holds the outer surface of the core covered with the connection film. A film thickness of the conductor film is equal to a skin depth and thus, it is possible to inexpensively maintain reliability, and to prevent radiation efficiency from being lowered.
