Reflectance and wavelength
WebThe absorption process and the wavelength dependence enables scientists to derive information about the chemistry of a mineral based on the reflected light. Even the human eye can be considered a crude reflectance spectrometer (11). This is because when the eye looks at a surface it detects color. WebHere, a “chemical unit co-substitution” method is used to improve the near-infrared (NIR) emission of phosphors, using [Zn 2+ –Ge 4+] to co-substitute [Ga 3+ –Ga 3+] sites to reduce crystal field splitting to affect the structure of gallium oxide.A series of broadband NIR phosphors are synthesized by a high-temperature solid-phase method, and their phase …

WebAn original method enabling us to characterize the non‐uniformity of thin‐film thickness is described. This method employs the interpretation of data obtained by multiple‐wavelength reflectometry (MWR). Within this MWR method the values of the reflectance are measured for several wavelengths in many points lying along the area of the film. The spectral … WebGround-based sensors are able to efficiently provide information on nutritional status using leaf spectra reflectance. This research aims to establish a novel cost-effective and non-destructive approach for rapidly estimating the status of nitrogen (N), phosphorus (P), and potassium (K) in apple tree leaves based on Visible/Near-infrared (Vis ...
