Silicon quantum dot

<p>Silicon quantum dots are metal-free biologically compatible <a href="/facts/Quantum_dot/K5Ytv8Yw">quantum dots</a> with <a href="/facts/Photoluminescence/L1u2PJIa">photoluminescence</a> emission maxima that are tunable through the visible to near-infrared spectral regions. These quantum dots have unique properties arising from their <a href="/facts/Direct_and_indirect_band_gaps/9T1kkc6y">indirect band gap</a>, including long-lived luminescent excited-states and large <a href="/facts/Stokes_shift/kk568kTg">Stokes shifts</a>. A variety of <a href="/facts/Disproportionation/67QMkXrV">disproportionation</a>, <a href="/facts/Pyrolysis/h1cEegI7">pyrolysis</a>, and solution protocols have been used to prepare silicon quantum dots, however it is important to note that some solution-based protocols for preparing luminescent silicon quantum dots actually yield <a href="/facts/Carbon_quantum_dots/rN7CU7qy">carbon quantum dots</a> instead of the reported silicon. The unique properties of silicon quantum dots lend themselves to an array of potential applications: <a href="/facts/Biological_imaging/7XHksEj4">biological imaging</a>, <a href="/facts/Luminescent_solar_concentrator/umTmE4ry">luminescent solar concentrators</a>, <a href="/facts/Light-emitting_diode/gE8x4MDb">light emitting diodes</a>, <a href="/facts/Sensor/RN8SXbjs">sensors</a>, and <a href="/facts/Lithium-ion_battery/3L22xFhB">lithium-ion battery</a> anodes.
