实时调谐的染料封装在胶体晶体的发射特性，通过原位修改的拒绝波长的证明。如图所示，使用机械致变色调谐来改变由涂覆有光致发光染料罗丹明-B的静电自组装单分散聚苯乙烯颗粒组成的水凝胶包封的结晶胶体阵列的发射光谱。
Real-time tuning of the emission characteristics of a dye encapsulated in a colloidal crystal through in-situ modification of the rejection wavelength is demonstrated. Mechanochromic tuning is used to modify the emission spectra of hydrogel-encapsulated crystalline colloidal arrays composed of electrostatically self-assembled monodisperse polystyrene particles coated with the photoluminescent dye Rhodamine-B, as shown in the Figure.
