Negative thermal expansion in Sc2Mo3O12:Sm3+ for white LEDs and unveiling the impact of phase transition on cryogenic luminescence
Sc2Mo3O12:Sm3+ phosphor was explored for white LED with improved CRI and precise color coordinates for indoor plant growth. The green emission of monoclinic Sc2Mo3O12 phase at 80 K diminished on transition to the orthorhombic phase at RT.
Fine tuning the steric hindrance of the Eu(II) tris(pyrazolyl)borate complex for a blue organic light-emitting diode
A sky-blue OLED based on a Eu(II) complex Eu–tBu shows an EQEmax of 15.7% and a Lmax of 52 240 cd m−2.
