مستخلص: | The new-fangled red-emitting phosphor Sm3+: Bi2La4O9via the simplistic solid-state route is Characterised by X-ray diffraction (XRD). The synthesised samples bear identify with the monoclinic unit cell of C2/mspace group. The optical traits interpreted by the UV–visible analysis and spectrometric evaluations, as well estimates the decay lifetimes. The f-f traits of Sm3+408, 425, 480 and 491 nm impact the characteristic emission lines. Fine tuning the doping concentration of Sm3+ions favours the sample phosphor to realize efficaciously tunable red colour. It is also inferred from the CIE coordinate chart that the single dopant Sm3+with squat CCT and soaring colour clarity counts lies in the red region. The revelation of Bi2La4O9:Sm3+phosphors are nearly the same as the predetermined values of the Nichia corp red-light emitting diodes. The computed calculations of colour coordinates and the CCT of Sm3+ions observed to be below 3000k for warm light when excited by 491 nm wave length. This authenticate the Sm3+: Bi2La4O9phosphor pertinently tunable candidate with the potential for efficient red display and solid state lighting appliances. |
