SUPERLATTICE THERMOELECTRIC MATERIAL AND THERMOELECTRIC DEVICE USING SAME

The present invention relates to a phosphor and, more particularly, to a yellow light-emitting phosphor and a light-emitting device using the same. The yellow light-emitting phosphor of the present invention comprises: a first phosphor including at least one of Lu[3]Al[5]O[12]:Ce and SrSi[2]O[2]N[2,and a second phosphor which is mixed with the first phosphor to form a mixture, includes Ba2Si5N8, and is excit]ed by near ultraviolet or blue light to emit light having a peak wavelength in the range of 550 to 590 nm, wherein the mixture of the first phosphor and the second phosphor may be excitedby the near ultraviolet or blue light, and emit yellow light. 本发明涉及一种磷光体，更特别地涉及一种黄光发射磷光体和使用其的发光装置。本发明的黄光发射磷光体包含：第一磷光体，包含LuAlO:Ce和SrSiON中的至少一者；和第二磷光体，与所述第一磷光体混合以形成混合物，包含BaSiN，且由近紫外光或蓝光激发以发射具有在550nm至590nm范围内的峰值波长的光，其中所述第一磷光体和所述第二磷光体的混合物可以由近紫外光或蓝光激发，并且发射黄光。
