Generalized wet-chemical processing of phosphor monospheres and the effects of composition on photoluminescence
Basic carbonate monospheres of various lanthanide combinations are successfully synthesized by the urea-based homogeneous precipitation technique, which are then converted into well dispersed phosphor particles that emit diverse colours. Sequential precipitation is commonly observed for these mixed cation systems, calling for adequate annealing of the basic carbonate precursors to attain cation...
متن کاملRed (SrCa)AlSiN3: Eu Nitride Phosphor Particle Size of Phosphor Converted Warm White LEDs
Red (SrCa)AlSiN3: Eu nitride phosphor with different particle sizes were characterized based on physical and luminescent properties, then packaged into Chip-On-Board (COB) Warm White Light Emitting Diode (LED) modules to investigate the influence of particle size on packaging parameters and optical output of the COB LED devices. The phosphor particle sizes investigated were 10μm, 12μm and 14μm,...
متن کاملLuminescence properties and warm white LED application of a ternary-alkaline fluoride red phosphor K2NaAlF6:Mn4+ .
Herein, a Mn4+ ion doped complex ternary-alkaline fluoride red phosphor K2NaAlF6:Mn4+ has been synthesized through a facile two-step co-precipitation method at room temperature. The crystal structure, morphological properties and influence of the dopant concentration, temperature and humidity on luminescence properties as well as the performance of the as-synthesized phosphor used in white ligh...
متن کاملNew Ce3+-activated thiosilicate phosphor for LED lighting-synthesis, luminescence studies, and applications.
A new Ce(3+)-activated thiosilicate phosphor, BaLa2Si2S8:Ce(3+), was synthesized by using solid-state methods in a fused silica ampule and found to crystallize in the structure type of La2PbSi2S8. The crystal structure has been characterized by synchrotron X-ray diffraction and refined with Rietveld methods. This novel cyan-emitting phosphor can be excited over a broad range from UV to blue lig...
متن کاملControlled processing of (Gd,Ln)2O3:Eu (Ln = Y, Lu) red phosphor particles and compositional effects on photoluminescence
Synthesis of (Gd0.95-x Ln x Eu0.05)2O3 (Ln = Y and Lu, x = 0-0.95) powders via ammonium hydrogen carbonate (AHC) precipitation has been systematically studied. The best synthesis parameters are found to be an AHC/total cation molar ratio of 4.5 and an ageing time of 3 h. The effects of Y3+ and Lu3+ substitution for Gd3+, on the nucleation kinetics of the precursors and structural features and o...
