The Light Features and Bredigite Layout for Orthosilicate Phosphor in WLED Devices
We created a green phosphor Ca14-xEuxMg2[SiO4]8 or CMS: Eu2+ to be utilized in WLED devices. The phosphor offers a wide spectrum achieving the highest value of 505 nm when excited at 400 nm, as a result of a shift between the excited state of 4f 65d and the ground state of 4f 7 in an io...

| description | We created a green phosphor Ca14-xEuxMg2[SiO4]8
or CMS: Eu2+ to be utilized in WLED devices. The phosphor
offers a wide spectrum achieving the highest value of 505 nm when excited at
400 nm, as a result of a shift between the excited state of 4f 65d
and the ground state of 4f 7 in an ion of Eu2+.
The interactivity of dipole-dipole appeared to be a primary power shift for the
electrical multipolar nature of the phosphor. We acquired a critical distance
measured at 12.9as well as 14.9 via a critical Eu2+ concentration as well
as the Dexter hypothesis on power shift. Via an encapsulant, we combined CMS:Eu2+
as well as a phosphor in red with a LED device having a value of 395 nm and managed to acquire white
illumination having a CRI value measured at 91 at a 20-milliampere forward bias
current. In addition, we also examined the layout as well as the light features
in CMS:Eu2+. |
