"highly efficient/ stable pure-red emission... modulates bandgap through lattice distortion but decomposes under high temperature, overcome using hot-injection, acid–base equilibrium between ethylammonium carbonate/ oleic acid survives hot-injection synthesis' harsh conditions... exhibits lattice expansion, reduced defect densities, near-unity photoluminescence quantum yield... tunable emission across 630-650 nm range... 26.1% maximum external quantum efficiency (vs. 9.9), also other quantum dot compositions, ranges"
