Beschreibung
Zusammenfassung:	The present invention relate generally to near infrared luminescent material excited by near infrared ray and method of manufacturing the same, and to be more specific, the method comprising: a) mixing, as host material, a compound including ytterbium salt, yttrium salt, silicon salt and vanadium salt or a compound including ytterbium, yttrium oxide, silicon dioxide and vanadium oxide with one or more species of a lanthan metal oxide selected from a group comprising Nd 3+ and Er 3+ as an activation agent (M) or metal, or proceeding without an activation agent; b) increasing the temperature of compounds obtained from a) step and heat-treating at 900 ~ 1100 ℃ to manufacture a luminescent powder; and c) crushing the luminescent powder using a crusher.
