Fig. 4

a Experimental and simulated radioluminescence (RL) spectrum of nanocomposites loaded with hetero-ligand Zr-DPT:DPA-8% and homo-ligand Zr-DPA nanocrystals fabricated by using polydimethylsiloxane (PDMS) as host polymer matrix (0.5% wt, 1 mm thickness) under X-ray exposure (digital pictures). b Zr-DPT:DPA-8% nanocomposite photoluminescence (PL) intensity decay recorded at 430 nm (top) and 540 nm (bottom) as function of the temperature under pulsed laser excitation at 405 nm. c RL spectrum of the Zr-DPT:DPA-8% nanocomposite as a function of the temperature. d Simulated output emission spectrum and efficiency (β) as a function of the scattering level (from 0 cm−1 to 20 cm−1) in a 10 × 10 × 5 mm scintillator. Dashed lines depict the single molecule spectrum of the DPA (top) and DPT (bottom) chromophores for reference.
