Power-dependent lasing spectra of CdS NBs at room temperature, the inset a shows the trend of lasing emission peak, the inset b is integrated peak intensity as a function of excitation power, and the inset c represents the PL intensity of CdS NBs and NWs plots as a function of time, both samples excited under 355 nm pulsed laser with the power density of 12.8 W/cm2
