Probe into the reflection from GaP nanoparticles via different solutions of radiative transfer equation

Synthesis, Structure, and Optical Properties of LiEu(PO3)4Nanoparticles

“…The reflectance absorption spectra were measured at room temperature, covering the spectral region of 200−700 nm, and were corrected according to the Kubelka−Munk equation . Figure presents the representative results of the measurements for the LiEu(PO 3 ) 4 nanocrystalline sample sintered at 800 °C.…”

Determination of spin-orbit splitting Δ 0 of valence band at Γ for gallium phosphide nanoparticles using fluorescence and infrared spectroscopes

“…The detailed synthetic procedure was reported originally elsewhere [4]. Therefore, no modification of that procedure will be described here.…”

“…Up to now, little is known on the effect of cluster size on the spin-orbit interaction for most type-IV and type-III-V semiconductors. Zhang et al measured the reflection and absorption spectra of GaP nanoparticles [4]. Although the indirect energy gap (E g,ind , Γ 15 -X 1 ), direct energy gap (E g,dir , Γ 15 -Γ 1 ), and higher-energy transition (E 1 , L 3 -L 1 ) can be estimated from the threshold contributions and saddle-point edge, it is impossible to obtain the spin-orbit splitting Δ 0 from these features of continuum band absorption or reflectance in GaP nanoparticles.…”

Ellipsometric analysis and optical absorption characterization of gallium phosphide nanoparticulate thin film

“…Wide-band-gap semiconductors have attracted a great deal of attention because they are strong candidate materials for light emitting diodes (LEDs) operating in the blue-to-ultraviolet region. [1] Gallium phosphide (GaP), is a popular semiconductor material [2] and is considered to be a wide-band-gap semiconductor, making it a good candidate for roomtemperature device applications. GaP has potential for ultraviolet, blue, and blue-green detection applications from 250 nm to 500 nm.…”

“…[1,7−10] It has been inferred that GaP nanoparticles exhibit a direct transition and an indirect transition from their ultraviolet and visible (UV-vis) spectra. [1,10] The ratio of the absorption and scattering coefficients of the GaP nanoparticles layer has also been calculated from its reflection spectrum via a radiative transfer theory, whose curves exhibit the energy band gaps of GaP nanoparticles. [1] The design, manufacture and study of nanoparticle-based films have become particularly attractive because of the potential technological applications, such as catalysis, microelectronics, molecular recognition and chemical sensing.…”
