Abstract: A fine particle containing a rare earth metal, characterized in that it is excited by a light having a wave length within the range of 500 nm to 2000 nm to undergo up-conversion light emission; and a fluorescent probe which comprises the fine particle containing a rare earth metal and a substance capable of bonding specifically with the fine particle containing a rare earth metal. The above fine particle can be exited by a light which does not adversely affect a material to be analyzed, and undergoes light emission with stability and with good efficiency.
