| 摘要 |
The present invention relates to a fluorescent body capable of being used for an LED lighting, more specifically an oxy-fluoride based fluorescent body with improved light emitting efficiency in a 390-470 nm light source for optical pumping by substituting terbium (Tb), lanthanum (La), and gadolinium (Gd) of the fluorescent body. The oxy-fluoride based fluorescent body of the present invention can be applied to light emitting devices including a light emitting diode, a laser diode, a surface emitting laser diode, an inorganic electroluminescence element, and an organic electroluminescence element. |
