This supplier offers a range of glow in the dark materials including paints,
powders, phosphors and some coated or formed products.
They claim that the performance of their products is far better than what is
usually available at retail level.
Glow durations up to 24 hours claimed, depending on formulation.
Solvent based paints not exported internationally due to Hazmat regs.
Not cheap but I imagine that 'a little goes a long way'.

As ever, YMMV, E&OE, DNBSFoM.
