Synthesis and characterization of thermostable Dy3+-doped La5NbMo2O16 yellow-emitting phosphors for w-LEDs

Cool green-emissive Y2Si2O7:Tb3+ nanophosphor: auto-combustion synthesis and structural and photoluminescence characteristics with good thermal stability for lighting applications

“…Additionally, McCamy's third-order polynomial was utilized for computing the CCT values based on the Kelvin (K) scale to assess the quality of light, given by eqn (22) . 67 CCT = −437 n 3 + 3601 n 2 − 6861 n + 5514.31 here, ( x , y ) are CIE coordinates, n = ( x − x e )/( y − y e ) is the inverse slope line, and x e and y e = 0.332 and 0.186 are the values of chromaticity epicenters. The values of photometric variables such as CIE, CP and CCT of all the synthesized Y 2− x Si 2 O 7 : x Tb 3+ ( x = 0.01–0.06 mole) phosphors are summarized in Table 5 .…”
