Disclosed are a phosphor, in particular, a red light emitting phosphor, a method for producing the same and a light emitting device package including the same. Provided is a red light emitting phosphor emitting light having a main absorption band in a blue wavelength range and a main peak in a red wavelength range, the red light emitting phosphor being represented by the following Formula 1.(SrEu)LuO&#x2003;&#x2003;[Formula 1]

Red light emitting phosphor, method for producing the same and light emitting device package including the same

Disclosed are phosphors and, more particularly, yellow light emitting phosphors and light emitting device packages using the same. The yellow light emitting phosphor includes a first phosphor including at least one of LuAlO:Ce, SrSiON, and &#x3b2;-type SiAlON and a second phosphor mixed with the first phosphor to form a mixture, the second phosphor including &#x3b1;-type SiAlON(Li-&#x3b1;-SiAlON) containing Li as a metal component, wherein the second phosphor emits light having a central wavelength in a range of 550 nm to 590 nm by being excited by near ultraviolet (UV) or blue light, The mixture of the first phosphor and the second phosphor is excited by the near UV or blue light to emit yellow light.

Yellow light emitting phosphor and light emitting device package using the same

A semiconductor device, and more particularly a light emitting device package usable with a lighting apparatus is disclosed. The light emitting device package comprises a package body, a light emitting device located on the package body, the light emitting device emitting light having a first wavelength band, a transparent substrate located over the light emitting device with a distance therebetween, a wavelength conversion layer located on the transparent substrate, wherein the wavelength conversion layer absorbs and converts at least a part of the light having the first wavelength band into light having a second wavelength band, and a color calibration layer located on the wavelength conversion layer, the color calibration layer calibrating color of the wavelength conversion layer.
