“…(2) Borate matrix, which is easy to synthesize and stable in physical and chemical properties. However, it has shortcomings such as short emission wavelength and serious aging phenomenon [15]. 3Silicate matrix, which has good light permeability, high luminous efficiency, and low production cost, but the silicate itself has poor chemical stability, and it is necessary to study whether it can widely use white LED [16].…”

As one of the important raw materials for LED products, phosphors play an important role. At present, the spectrum of LED phosphors lacks red light, resulting in poor quality of white LED products and a low color rendering index (Ra <80), which affects lighting effects. To solve this problem, we synthesized the SrGd2O4:Eu3+ red phosphor by a high-temperature solid-phase method. The structure and luminescence properties of SrGd2O4:Eu3+ red phosphors were studied by means of X-ray diffraction (XRD) measurements of their emission and excitation spectra, and their spectra were analyzed. We also studied the Eu3+ doping concentration with the best luminous efficiency and the color coordinate of the SrGd2O4:Eu3+ phosphor. The experimental results show that SrGd2O4:Eu3+ is a new red phosphor material that can be used for near-ultraviolet or blue-light excitation and has good practicability.

“…Miranda et al observed that ZnO/SiO 2 nanocomposites emitted a highly blue emission spectrum. Moreover, it was found that the PL intensity, enhanced by doping ZnO–SiO 2 nanocomposites with 1.25% Eu 3+ . Belache et al showed that PL of ZnS:Cu quantum dots (QDs) embedded in silica thin films has a new feature, two emission bands (blue and green colors), due to defects induced in both ZnS:Cu QDs and silica matrix by Cu doping which played key roles in the luminescence properties of PL bands .…”

The synthesis of ZnO/SiO2 nanocomposite doped with Co, Cu and Mn nanoparticles were performed using sol‐gel method. Rietveld refinement analysis was done for the X‐ray diffraction data and results showed that all samples are single wurtzite hexagonal phase and have an average crystallite size ~14 nm. The lattice parameters, bond length, crystallite size, microstrain, dislocation density and the system volume were studied in details. Transmission electron microscopy technique showed that nanoparticles characterized by an elliptical shape. Fourier transform infrared and scanning electron microscope techniques proved the presence of SiO2 in the system. The energy gap values of both undoped and doped samples with Co, Mn and Cu were 2.84, 2.47, 2.71 and 2.8 eV, respectively. Photoluminescence spectra for undoped and doped ZnO/SiO2 were investigated in details.
