WebA refractometer, a smart cup, and a refractive index measurement method, which relate to the field of liquid refractive index measurement. The refractometer comprises a light source module (1), a reflective module (2), a lens module (3), a photosensitive area array (4), a control module, and a processor, wherein the reflective module (2) is used to receive a … WebΔα=(dαAp)(ΔP)dαEp +(dαAn)(ΔN)dαEn Δ α = ( d α A p) ( Δ P) d α E p + ( d α A n) ( Δ N) d α E n. where, Δn is the refractive index change. Δα is the absorption coefficient variation in cm-1. ΔP is the hole concentration change in cm-3. ΔN is the electron concentration change in cm-3. dαAp d α A p is 6e-18 for 1.55 um.

WebFaster refractive index modulation experiments were performed by alternating incubation of ZIF-8 thin films in toluene and ethanol for 60 minutes each. For the UV/Vis and ellipsometry studies, an ethanol-stored ZIF-8 film on glass (for UV/Vis spectroscopy) or silicon (for ellipsometry measurements) was incubated several times in toluene, each ...
