The control area was 32744.3hm2, which was 98.2% of the suitable control area in Inner Mongolia Daxing’an Mountains and 75%of the suitable area in Inner Mongolia respectively. Dosage was 1125 g/hm2. Control effectiveness was above 95%, the larvae density decreased from 52.5 to 0.94 per 50cm sample twig and direct economical benefit was 3,935,420 Chinese yuan.展开更多

The enhancement factors of the excitation and the relaxation processes are deduced. The excitation can be enhanced more than 100 times at 315 nm. The enhancement factor of the emission can reach up to 9 at a center wavelength of 400 nm.展开更多
