Negative thermal expansion in Sc 2 Mo 3 O 12 :Sm 3+ for white LEDs and unveiling the impact of phase transition on cryogenic luminescence

Sc 2 Mo 3 O 12 :Sm 3+ phosphor was explored for white LED with improved CRI and precise color coordinates for indoor plant growth. The green emission of monoclinic Sc 2 Mo 3 O 12 phase at 80 K diminished on transition to the orthorhombic phase at RT.
