A green phosphor including: (i) an inorganic phosphor particle; and (ii) neodymium-containing particles attached on a surface of the inorganic phosphor particle, wherein the green phosphor has a light-emission local maximum wavelength in a range of from 500 nm to 570 nm.

Green phosphor, phosphor sheet, and light-emitting device

A thermally conductive sheet including a sheet body that is a cured product of a thermally conductive resin composition including a binder resin and carbon fibers covered with insulating coating films, wherein the carbon fibers exposed on a surface of the sheet body are not covered with the insulating coating films and are covered with a component of the binder resin.

Heat conduction sheet, heat conduction sheet manufacture method, heat radiation member, and semiconductor device

In order to suppress the chromaticity shift and corrosion associated with the deterioration of a sulfide phosphor particle, this phosphor sheet is produced using a phosphor particle-containing resin composition which comprises: covered phosphor particles; polymerizable compound; and a polymerization initiator. The covered phosphor particles are obtained by covering phosphor particles with silicon dioxide films, wherein among the phosphor particles, at least sulfide phosphor particles are covered with silicon dioxide films that contain a metal oxide powder. Thus, the phosphor sheet can be inhibited from emitting a sulfur-based gas, and exhibits a minimized chromaticity shift, even when the phosphor sheet is present in such a manner that the edge of the phosphor layer of the sheet is in an exposed state.

Phosphor sheet

A fluorescent substance, represented by the following general formula (1):Ca(SeS):Eu&#x2003;&#x2003;(1)where y is a value in the range of 0.5 to 1,wherein an absolute value of a difference between an optimal value (nm) of an emission peak wavelength corresponding to the value of y, and a measured value (nm) of the emission peak wavelength is 5 nm or less, and wherein an absolute value of a difference between an optimal value (nm) of a full width at half maximum of emission corresponding to the value of y, and a measured value (nm) of the full width at half maximum of emission is 6 nm or less.

Fluorescent substance and production method thereof

A coated phosphor includes a sulfide phosphor coated with silicon dioxide film. The silicon dioxide film includes a metal oxide powder. The metal oxide powder includes a zinc oxide powder such that less than 20 parts by mass of the zinc oxide powder relative to 100 parts by mass of the sulfide phosphor is blended therein.
