UV‐excited blue‐ to green‐emitting Tb3+‐activated sodium calcium metasilicate colour tunable phosphor for luminescence devices

“…Recently, the pc‐w‐LEDs available in the market have used phosphors with micro‐sized particles to achieve intense luminescence, which indicated that the proposed NCMS:Tb 3+ phosphors may provide better performance in terms of commercial usage. [ 36 ]…”

“…The optical band gap can be calculated by extrapolating the line to provide better performance in terms of commercial usage. [36] 3.5 | Photoluminescence analysis ion. [37,38] The inset in Figure 5 at a fixed emission wavelength of 542 nm in the range 300-400 nm and discerned less intense peaks.…”

Investigation of Structural, Morphological and Luminescent Features of Eu³⁺ Activated Molybdate Based Phosphor for W-LED Applications

“…4, the calculated CCT values for NBM: 1.0 mol% Eu 3+ phosphor excited with 464 nm wavelength is 2334 K. The phosphor materials showing CCT values are greater than 5000 K, which are suitable for cool white light applications. However, values under 5000 K are much more serviceable in production of warm white light [22]. Therefore, the as-synthesized NBM phosphor may have a good potential to be utilized for warm w-LED applications, as the evaluated CCT values are lower than 5000 K. Indeed, the colour purity of the synthesized phosphor is an essential criterion to achieve optimal materials for w-LED applications and can be evaluated by the formula mentioned below [23] 𝐶𝐶𝐶𝐶𝐶𝐶𝐶𝐶𝐶𝐶…”

Thermally stable and color-tunable bi-activated (Dy3+/Eu3+) alkaline earth metasilicate phosphor for luminescent devices

“…Over the past few decades, inorganic material-based phosphors with extensive optical properties have been investigated for various solid-state lighting applications, such as w-LEDs, multicolour displays, solar cells, and temperature sensors. [1][2][3] Especially focused on w-LEDs, the inorganic luminescent device technology based on these phosphors has replaced incandescent and uorescent lamps. 4,5 Owing to their plethora of merits, including lifespan, high durability, affordability, and environmental friendliness, phosphor-based luminous devices have attracted the attention of researchers.…”
