Light Reflection by Cuticles of Chrysina Jewel Scarabs: Optical Measurements, Morphology Characterization, and Theoretical Modeling

引用

Optics and Photonics Journal 2016年第7期6卷 146-163页

作者： W. E. Vargas M. Hernández-Jiménez E. Libby D. E. Azofeifa C. Barboza Á. Solis Centro de Investigación en Ciencia e Ingeniería de Materiales & Escuela de Física Universidad de Costa Rica San José Costa Rica Academia Nacional de Ciencias de Costa Rica San José Costa Rica Centro de Investigación en Ciencia e Ingeniería de Materiales and Escuela de Química Universidad de Costa Rica San José Costa Rica Centro de Investigación en Estructuras Microscópicas Universidad de Costa Rica San José Costa Rica Museo Nacional de Costa Rica San José Costa Rica

Cuticles of some Chrysina scarabs are characterized by flat, graded, and twisted structures of nanosized chitin fibrils. As inferred from SEM images, each species has its own spatial period or pitch P which is dependent on the depth z through the cuticle. From Berreman’s formalism, taking into account the corresponding P(z) dependence, we evaluate reflection spectra of C. aurigans and C. chrysargyrea scarabs. The spectra display the main spectral features observed in the measured ones when small sections of the cuticles are illuminated with non-polarized light, for wavelengths between 300 and 1100 nm. By considering these twisted structures as 1D photonic crystals, an approach is developed to show how the broad band characterizing the reflection spectra arises from a narrow intrinsic photonic band width, whose spectral position moves through visible and near infrared wavelengths. The role of the epicuticle that covers the twisted structures is analyzed in terms of a waxy layer acting as an anti-reflecting coating that also shows low levels of light scattering.

Vertical-assembly of cellulose nanocrystals for hiding and reading information

第十一届全国高聚物分子与结构表征学术研讨会

作者： Lin Gan Na Feng Jin Huang School of Chemistry and Chemical Engineering Southwest University

Saving the information in the materials who can display different states in different conditions is an important optical method of information *** and stimulation-responsive dyes are two typical materials in this method,whereas they usually suffer problems of photobleaching and aggregation-induced quenching. By contrast, assembly materials with periodicities equal to the wavelength of visual light own structural colors, which are free of those problems. In this work,the structural color of cellulose nanocrystals（CNCs） assembly was successfully controlled in ultraviolet region, which hide the information of patterned CNC assembly films under natural light. Periodically arranged CNCs could even enhance scattering, which was similar to the photonic crystals. This feature made the hided information of the CNC films readable as enhanced scattering blue light under an ultraviolet lamp. By an evaporation-induced method, CNCs could arrange vertically,which removed the usual chirality and iridescence of assemble films of CNCs as rod-like nanoparticles. This resulted in a structural single color, which prevented the information from being misread due to the iridescence.
