A new photonic material is presented: “photonic glass” . This is a 3D completely disordered solid arrangement of monodisperse dielectric spheres (see figure). Monodispersity ensures single‐sphere optical resonances to be observed. Very thick (from tenths to few millimetres) uniform samples can be grown by attenuating the inter‐sphere interaction. Thin (correlated) disordered films can be grown by vertical convective deposition and selective etching of binary colloidal suspensions.
