Suppressing the Mechanochromism of Flexible Photonic Crystals [PDF]
Optics Express, 2023 We present flexible photonic crystal slabs (PCS) obtained by sputtering of a dielectric 100 nm Nb2O5 high refractive index layer onto a flexible nanostructured polydimethylsiloxane (PDMS) substrate with 370 nm grating period. The PCS exhibit a guided mode resonance at around 650 nm.

Force-light-heat stimulation-induced multicolor chromism and multifunctional applications of europium tungstate phosphor [PDF]
Nature CommunicationsStimulus-responsive chromogenic luminescent materials are promising for security and optical storage, yet force-induced color change in inorganic materials remains rarely reported. Here we report a europium tungstate that exhibits mechanochromism, driven
