<p>A purpose of the present invention is to provide fine fluorescent quantum-dot particles which have high durability, a small size, and a high luminance. The other purpose of the invention is to show a method for applying the particles to fluorescent reagents for use in the biological field and to the field of electronic materials, etc. The fine fluorescent particles comprise quantum dots which comprise Cd and Se and which have been coated with a thin film that has an average thickness of 3 nm or less and that comprises a silica glass formed from a silicon alkoxide. The fine fluorescent particles can be produced by a method including a step in which quantum dots comprising Cd an Se are stirred together with an alkoxide in a hydrophobic atmosphere for a certain period to thereby silanize the alkoxide. It is preferable that the method include, after the silanization step, a step in which a silica glass layer is gradually deposited using a reverse micelle method, etc.</p> |
