Colloidal-Crystal Laser Using Monodispersed Mesoporous Silica Spheres

Monodispersed mesoporous silica spheres (MMSSs) are silica colloid particles with uniform mesopores and particle diameters. MMSS ionic colloidal crystals can be fabricated by self‐organization and immobilization using a hydrogel. From measurements of the emission light of the gel‐immobilized MMSSs w...

Zusammenfassung:Monodispersed mesoporous silica spheres (MMSSs) are silica colloid particles with uniform mesopores and particle diameters. MMSS ionic colloidal crystals can be fabricated by self‐organization and immobilization using a hydrogel. From measurements of the emission light of the gel‐immobilized MMSSs where a laser dye was incorporated, laser emission occurred through the excitation by a YAG laser.
